Operating Manual for SBR small wastewater treatment systems- Storage of the supply water,- Compensation of volume- and concentration-related fluctuations in inflowing wastewater.The wastewater treatment plant is operated by means of a microprocessor control that drives the aeratorand the air distribution for the different lifts via solenoid valves.Your competent water authority has determined limit values for the water quality of the treatedwastewater. Accordingly, you have purchased a plant of the effluent class which definitely complies withthese limit values. Depending on the certification, both the interval between the prescribed maintenances(at intervals of 4 or 6 months) and the scope of the effluent values to be verified vary.The following table provide an overview of the effluent values of KLARO.KLARO values:KLAROvaluesDegree ofefficiencyCOD BOD 5 NH 4 -N N inorg SS FC germs P tot39 mg/l 9 mg/l 6,1 mg/l 18,7 mg/l 15 mg/l 1,9/100ml 0,4 mg/l94,6 % 97,3 % 84,4 % 67,4 % 96,2 % 99,9 % 95,0 %4.1. Plants for carbon elimination (effluent classes C)This method is a sequence of five work steps that are carried out one after the other and are repeatedseveral times a day (normally four times).- Work step 1 (valve 1) : feed- The raw wastewater stored temporarily in the sludge storage is led to the SBR reactor via an airlift. This reactor is positioned in such a manner that only water free of solids is pumped. Bymeans of a special design of the lift, a minimum water level in the sludge storage is guaranteed.Thus, the limitation of the water level using further components (e.g. by means of a float switch)is not necessary.- Work step 2 (valve 2): ventilationDuring this work step, the wastewater is aerated and mixed. The ventilation is provided bydiaphragm tubes or plates installed on the chamber bottom. The ventilation device of the plant issupplied withambient air by anexternallyinstalled controlcabinet. Therequired air isgenerated by anaerator. Theventilation isnormally operatedintermittently. Figure 1: Diaphragm tube aerator Figure 2: Diaphragm plate aeratorKLARO GmbH 11

Operating Manual for SBR small wastewater treatment systemsThis ventilation causes two effects at the same time:• The micro-organisms of the activated sludge are supplied with oxygen that is required fortheir metabolic activity and, thus for the degradation of the contaminants.• There is intensive contact between wastewater and bacteria.- Work step 3: settling phaseThis work step constitutes a resting phase, during which no ventilation takes place. Theactivated sludge can settle according to the principle of gravity (sedimentation phase). In theupper area, a clearwater zone develops and a sludge layer at the bottom. Any occurring floatingsludge is above the clearwater zone.- Work step 4 (valve 3): clearwater extractionDuring this phase, the biologically treated wastewater (clearwater) is pumped out of the SBRstep. This pumping process is carried out by means of air according to the airlift pump principle(air lift). The air lift is designed in such a manner that any occurring floating sludge on theclearwater layer is not pumped. A minimum water level in the SBR step is kept without anyfurther components.- Work step 5 (valve 4): excess sludge extractionDuring this working step, excess activated sludge by means of the air lift is led back from theSBR reactor chamber into the sludge storage chamber and stored there. This excess sludge ispumped close to the bottom of the SBR chamber.After this fifth work step has been completed, the treatment process can start again with work step 1.Four of the cycles described above are normally processed per day. An individual adjustment of theswitching times and the cycle number is possible after consultation with KLARO GmbH. This adjustmentmay only be carried out by an authorised specialised maintenance company.In addition to this, it is possible to manually switch the plant into the vacation mode. The vacation modeis a significantly reduced operation of the plant during longer periods of time without inflowingwastewater.By means of the KLplus control, the plant can be operated depending on the actual amount ofwastewater. For this, the fill-level detection must be activated by a specialist.Important: All chambers / containers must be aerated. This is normally performed by the wastewater linevented via the roof. If required, additional ventilation lines or ventilation openings must be installed. Indoing so, the ventilation lines must be positioned in such a manner that natural ventilation is possible(chimney effect).4.2. Plants with additional nitrogen eliminationThe nitrogen degradation is also carried out biologically by means of certain strains of micro-organisms.Plants with additional nitrification create, by means of particularly intensive ventilation, optimum livingconditions for nitrifying bacteria which convert ammonia to nitrate. In plants designed for additionaldenitrification, the circulation of the water and activation of the denitrifying bacteria are achieved by short12KLARO GmbH

Operating Manual for SBR small wastewater treatment systemsaeration periods at the beginning of the ventilation phase. These bacteria transform nitrate intoelementary nitrogen.4.3. Plants with additional phosphate eliminationThe phosphate precipitation is carried out by adding polyaluminium chloride in the SBR reactor. Aremovable supporting platform in the dome or on the dividing wall of the container is part of thephosphate precipitation unit. The precipitant canister is on this platform. The switch cabinet of the plant isequipped with a dosing pump. This dosing pump draws the precipitant out of the precipitant canister andreleases the precipitant in the SBR reactor. The precipitant is added during the feed phase of the reactor.The precipitant quantity required can be set by means of the dosing pump. The mixing takes place duringthe ventilation phase. Together with the phosphate, the precipitant forms an indissoluble compound thatsettles well in the container.The commissioning and handling of the pump is described in section 6.2.4.4.4. Plants with additional hygienisationThe additional KLARO UV module is used for sterilising the biologically treated wastewater. The germs inthe wastewater are removed by means of ultraviolet light (UV). This is an effective, economic andparticularly environmentally friendly method. UV light eliminates pathogenic micro-organisms withinseconds without residues, harmful by-products or reduction of quality through odours. The effect of theUV light is made use of by means of particularly effective UVC radiation (254 nm). Within a few seconds,it causes a photochemical reaction in the DNA (deoxyribonucleic acid) that is vital for all microorganisms.As a result of this, the micro-organism is either eliminated or its ability to multiply isdestroyed.With the UV dose values used for sterilisation, the UV irradiation does not cause any undesirable sidereactions. Since no disinfection-effective substance is added to the water due to the UV irradiation, thereare no depot effects after the water has passed the UV reactor.5. The control of the small wastewater treatment plantThe plant is operated by means of the control in the cabinet door (and/or in the interior of the cabinet withoutdoors cabinets). The control allows setting the operational parameters, displaying the operating statesand querying the plant parameters. Furthermore, the operating times can be programmed by aspecialised company.In the automatic mode, the contrast of the display can be changed by pressing the ESC and the arrowkeys at the same time.The following figures show the structure of the control units.KLARO GmbH 13

Replacing fusesBefore replacing the fuses, the plant must be switched off by means of the red main switch!In order to replace or check fuses, the control and machine cabinet must be opened with the keysupplied.The micro-fuses described above are on the rear of the control.Used fuses:Micro-fuseSupply line F1Consumer F2230 V / 50 Hz8 A, medium time lag2 A, time lagIn order to replace the micro-fuses, please proceed as follows:– Turn the head of the holder by applying slight pressure and using a slot screwdriverSL 1.0 x 5.5 for a quarter turn to the left (anti-clockwise).20KLARO GmbH

Operating Manual for SBR small wastewater treatment systems– Remove the head of the holder with the fuse.– Replace the fuse.– Insert the head with the fuse into the opening of the holder.– Gently press on the head of the holder using a screwdriver and fix the fuse by turning the headfor a quarter turn to the right (clockwise). Note:If you are not able to solve the problem, please contact your maintenance company or KLARO as soonas possible.5.4. Functional principle of the power outage detection deviceThe control is equipped with a power outage detection device that is powered by an integratedemergency power supply (buffering). In the delivery state, the emergency power supply is empty. It ischarged after the control has been switched on. In the event of a blackout, the charge of an emergencypower supply is sufficient for signalising the power outage for approx. 12 hours. If the emergency powersupply is not used to compensate power outages, the discharge of the emergency power supply isprevented from being discharged by means of a circuit.Important: In the event of a power outage, the setting of the time / date is supplied with power by meansof an additional buffering for a period of approx. 10 days. All saved data such as operating hours,programme settings etc. are preserved. If, however, date and time have not been set, weekly operatinghours of the aggregates are no longer saved. Future error messages are then saved with an incorrectdate.If the plant is disconnected from the mains (e.g. due to a blackout, when the internal fuse is blown orwhen separated from the wall socket), the detection device sends alternately an acoustic and visualsignal regardless of the actual cause. The device reacts to a power outage with a delay of five seconds.This prevents that short outages that often occur, for instance, during a thunderstorm, but do not impairthe overall function of the wastewater treatment plant, are unnecessarily signalled.- The five-second delay is followed by an intermittent with a read flashing signal. At intervals offive seconds, five flashing signals are continually sent with a beep for a period of approx.12 hours (with a completely charged emergency power supply).- Switching off the device is not possible in this state.When the mains voltage returns, the device is reset to the monitoring state without any further keys beingpressed and the control continues to run from the point at which it was interrupted. The fault messagedisappears automatically. When the emergency power supply is discharged, the operation of the plant isrestarted with a cycle pause.Blackout Attention: If the plant has been disconnected from the mains for more than 24 hours, thepurification of the existing wastewater is not possible or only possible to a very restrictedextent. Never switch off the plant (except for maintenance of plant components andfunction-restricting faults of the plant)KLARO GmbH 21

Underload detection (KLplus)Malfunction Attention: The activation of the fill-level-dependent mode must be carried out by amaintenance technician or an export. Any incorrect calibration of the plant can causethat the plant is permanently run in the saving mode (cycle pause)! In this case, properpurification is not possible!As standard, the KLplus control is equipped with a pressure sensor by means of which the fill level in thefirst chamber can be determined. This function is used for saving energy with low amounts of inflowingwastewater. This function is switched off in the delivery state. During commissioning, the plant is run inthe automatic mode regardless of the amount of inflowing wastewater.22KLARO GmbH

Operating Manual for SBR small wastewater treatment systems6.1.1. Functional principleThe water level is measured by means of thepressure in the feed lift during the feed phase. Ifthe water level in the sludge storage / buffer(chamber 1) exceeds a previously set fill-levelheight (“Fill-level detection setting“), the plant startsa purification cycle. If the fill level is not reached,the plant enters the cycle pause for a period of sixhours. During this cycle pause, the SBR reactor isonly aerated sporadically in order to keep thebacteria alive. If the previously set water level wasnot reached in the first chamber after foursubsequent measurements, the plant pumps, viathe excess sludge lift, water out of the reactor andback into the first chamber. After the water hasbeen pumped back, the plant measures the waterlevel again. With no or little inflowing wastewater,the reactor is thus also fed after a certain period of Figure 9: Drawing air lifter chargingtime. Hence, the normal purification performancecan also be maintained for a longer period of time in times of absence or underload.The number of the purification cycles performed can be queried via the menu item “operating hours“. Indoing so, the actually performed purification cycles are placed in relation to the cycles carried out in theautomatic mode (four cycles a day) and displayed as a percentage (capacity of 25 % to 100 %).6.1.2. CommissioningFall hazardDuring any work on the opened cover of the cesspit, there is a tripping and fallhazard!The open pit must be secured by means of suitable measures.The first chamber (sludge storage / buffer) equipped with the feed lift must be filled with water up to theheight at which a purification cycle is to be activated. This water level depends on the geometry of thecontainer and the connected PE. In the following table, the recommended buffer heights a above theminimum water level are stated for the different constellations.KLARO GmbH 23

Operating Manual for SBR small wastewater treatment systems6.1.4. Safety and fault messagesIf the sensor measures a value of less than 40 mbar, the message “Fault: min. fill level“ appears on thedisplay. In this case, the plant returns to the normal time-controlled mode. This can be attributed to eithertoo low a water level (≤ 40 cm) in the sludge storage / buffer or a leakage in the pressure or measuringhose. In this case, we recommend you to contact the manufacturer.6.2. Optional additional functions with extension cable (KLplus and KLbasic)By connecting an additional cable to the connection X3 or X4, the range of functions of the control can beextended.The following extensions are possible:• ST5 Connection of a phosphate dosing pump ( X3),• ST6 Connection of an external alarm unit ( X4), also for KLbasic,• ST7 Monitoring of a contactor for a three-phase current compressor ( X4),• ST8 Connection of a UV reactor ( X3).6.2.1. Connection of an external fault indicatorVia the potential-free output ST6, an external alarm unit such as an indicator lamp mounted to theoutside of the cabinet can be connected.More detailed information can be found in the MoAnl 10 Externe Warnmelder [InstInstr 10 externalalarm unit].6.2.2. Connection of a connector for switching the compressorIf the power supply of the installed compressor is higher than 6 amperes, a contactor is additionallyinstalled in the cabinet by means of which the compressor is driven. Via the input “Contactor monitoringST7”, the switching state of the contactor is monitored.6.2.3. Connection of a UV reactorVia the connection ST8, a downstream UV reactor can be connected to the control. More detailedinformation can be found in the MoAnl 11 UV-Anlagen [InstInstr 11 UV plants].6.2.4. Phosphate precipitation using the dosing pumpPrecipitant Attention: When swallowed, iron(III)-chloride is harmful to health and also irritatesthe skin. There is a risk of serious injury to the eyes.There is an explosion hazard in connection with alkali metals, allyl chloride and ethyleneoxide.Read the corresponding safety datasheet before using phosphate precipitants!When handling iron(III)-chloride, protective clothing must be worn.Keep precipitant containers away from unauthorised access by others and children.26KLARO GmbH

Operating Manual for SBR small wastewater treatment systemsPlants delivered with the phosphate precipitation function are equipped with a hose pump in the cabinet.A suction hose and a pressure hose are connected to the pump.The runtime of the hose pump is determined by the time set for the pump in the service menu. Theamount of the addedprecipitant thus depends onthe set time. The large pumpCompact is equipped with apotentiometer for setting theperformance. The table belowprovides an overview of thedosing possibilities. Therespectively required dosagecan be found in the respectivecertification (see CD).In order to commission theprecipitation unit, the containerwith the precipitant must beinstalled in a frost-proof place(e.g. machine cabinet, eitheron the dividing wall or in theFigure 10: System drawing precipitation unitdome-shaped manhole of theplant). The pressure hose andthe suction hose must also be installed in a frost-proof place. The pressure hose must be inserted intothe SBR reactor and positioned in such a manner in the reactor that the outlet opening is above thereactor tank and it is ensured that the precipitant falls directly into the wastewater to be treated and doesnot wet any components (aggressive chemical, risk of damage to the components!). The outlet openingmust, under no circumstances, be immersed into the water!• Insert the suction hose into the precipitant container to the extent that the suction from the bottomis ensured.• Connect the suction hose and pressure hose to the hose coupling nipples of the pump and fix themusing the union nuts.Under the menu item “Manual mode”, switch on the phosphate pump and check whether the precipitantis sucked correctly. If required, interchange the hoses at the connections.Reference values for setting thepump performanceP[ml/min]1 1.52 5.53 11.04 15.05 19.06 22.57 26.08 30.59 35.010 37.5Output: 5.5 ml/minFigure 11: Precipitant pump Compact Figure 12: Precipitant pump DSP 9911KLARO GmbH 27

Operating Manual for SBR small wastewater treatment systems7. Maintenance, servicing and operationThe plant must be switched on at any time. As operator of a small wastewater treatment plant, youare obliged to ensure the error-free operation of the plant. Almost all operational breakdowns cause adeterioration of the purification performance of the plant. Therefore, these operational breakdowns mustbe detected at an early stage and rectified by you or by a qualified maintenance technician.During any work on the opened cover of cesspit, there is a tripping and fallhazard!The open pit must be secured by suitable measures. Persons involved and/orthird parties may fall into the container! Children are particularly at risk!Fall hazard Due to the biological degradation processes in small wastewater treatmentplants, the generation of (possibly toxic) gases must be expected. Therefore,entering the plant must always be secured by a second person. In any case, afainted person must not be followed, but help must be sought as soon aspossible.High voltageFor activities other than operating the control, the maintenance switch must beset to 0 and/or the mains plug of the cabinet must be pulled out!Any maintenance and repair work on the cabinet system must be carried out by amaintenance technician or an electrician!28KLARO GmbH

Operating Manual for SBR small wastewater treatment systems7.1. Tasks of the operatorIn order to ensure an error-free operation, the following checks must be performed:7.1.1. Daily check- It must be checked whether the plant is run properly. This is the case if the operating indicator lamplights up green and no warning signal can be heard. A fault is displayed as described in chapter“control of the plant”. In the event of an incident, we ask you to read the liquid crystal display and toinform the service personnel about the displayed fault or, if possible, to rectify the fault yourself.7.1.2. Weekly checks- Checking the water levels; sludge must not enter the SBR chamber in an uncontrolled manner,- Checking the inlets and outlets for clogging (visual check),- Reading the operating hours counters of the aerator (total operating hours), the ventilation (valve 2)and the sludge return (valve 4), if required, also the operating hours counter of further aggregatesand recording them in the operation log,- Function control of the lifts and the ventilation via the setting “Manual mode”.7.1.3. Monthly checks- Visual check for any sludge overflow, blurring or discolouration in the outlet,- Checking the inlets and outlets for clogging (visual check),- Reading the operating hours counters of the aerator (total operating hours), the ventilation (valve 2)and the sludge return (valve 4), if required, also the operating hours counters of further aggregatesand recording them in the operation log,- Checking the air filter:The filter of the switch cabinet ventilation (ventilation grilles on the left and right side in the housingwall with an inside cabinet and/or on the rear with an outdoors cabinet) must be checked and, ifrequired, cleaned or replaced. For this, the grilles on the outside of the cabinet must be removed.The snap lock can be unlocked by applying slight pressure and using a screwdriver and the grille canbe removed by hand. The filter mat lies, without any further fastening means, in the ventilation pitand can be shaken out and/or blown out. The interval at which the filter of the aerator must becleaned or replaced depends on the extent of contamination caused by the atmospheric conditionsaround the application. In order to check or replace the filter on the compressor, the servicedocumentation of the compressor manufacturer provided in the annex must be complied with.- Checking the phosphate precipitation unit (if any): function control of the precipitant pump andchecking the fill level of the precipitant container,- Checking the function of the power outage alarm unit.7.1.4. Sludge drainageIn a small wastewater treatment plant, there are different types of sludge. Only the faecal sludge thataccumulates in the first chamber is removed. It consists of sedimented residues resulting from thewastewater treatment. In small wastewater treatment plants, the faecal sludge and/or sewage sludgeconsists of dead micro-organisms of the biological treatment stage and the settled solids resulting fromthe pre-cleaning. The height of the accumulated sludge in the sludge storage is measured by skilledmaintenance personnel using a sludge pipette. The plant is designed in such a manner that, withpermanent full-load operation and compliance with the operator and maintenance obligations, theKLARO GmbH 29

Operating Manual for SBR small wastewater treatment systemssludge storage room is large enough for at least twelve months. Low-load operation extends this periodof time accordingly. Timely sludge disposal is necessary in order to prevent the solids from entering thebiological stage in the event of increasing sludge production. Sludge regulation and disposal areimportant requirements for a good purification performance and long life of the small wastewatertreatment plant.The sludge disposal regulations are laid down by the local authorities. Either regular or demand-orientedsludge removal is required:- Regular sludge removal takes places on specific dates and is set by the local authorities to onceand/or twice a year depending on the type of the plant, size of the chambers and connectedinhabitants.- Demand-oriented sludge removal is flexible and takes place at shorter or longer time intervals. Inthis case, skilled maintenance personnel check the sludge level (sludge level measurement) andinform the competent disposal company about the date of the required sludge disposal. With a fillingof the sludge storage of 70 % at the latest, the sludge must be disposed of. In individual cases, theskilled maintenance personnel inform the operator who then arranges himself/herself a date for thesludge disposal.If the maintenance and the sludge removal coincide, the sludge may only be removed after themaintenance has been completed. The sludge removal must be recorded in the operating log. In thisrespect, please also read the instructions provided by your specialist company.For the sludge removal, the following aspects must be observed:In most cases, only the primary settlement chamber of the small wastewater treatment plant must beemptied. With an incorrect sludge regulation of the plant, the suction of the lower section of the tertiarytreatment chamber or the suction of the floating sludge from the surface may also be necessary.• First, the floating sludge is sucked from the surface; then, the suction tube is placed on thebottom of the pit,• A residual amount of water of approx. 10 cm should be left on the bottom of the primarysettlement chamber,• After the drainage has been completed, the primary settlement chamber must be refilledwith fresh water!Complete drainage of the small wastewater treatment plant only makes sense if an operationalbreakdown occurs for which the cause cannot be determined or if repair work must be performed belowthe water level inside the container. Whether such complete drainage is necessary is best decided bythe skilled maintenance personnel.It is essential that you, as operator of a small wastewater treatment plant, ensure that the correctchamber of the plant is pumped. Excessive pumping of sludge can interfere with the operation of asmall wastewater treatment plant and causes unnecessary costs!30KLARO GmbH

Operating Manual for SBR small wastewater treatment systems7.2. Maintenance and servicing by skilled maintenance personnelThe maintenance must be carried out by a specialised company (skilled personnel) 1 . For this, the owner ofthe plant must conclude a maintenance contract with a qualified specialist.Note! During retrofitting work or maintenance work on the electrical components of the plant, thecontrol cabinet must be disconnected from the power supply by means of a main switch ormaintenance switch of the plant. It must be ensured that the switch is protected against beingswitched on by means of a lock.The following work must be performed as part of the maintenance:- Inspection of the operating instructions including assessing that the plant works properly(target/actual performance comparison),- Checking the air filter of the aerator and the supply and exhaust air openings of thecontrol cabinet,- Maintenance of the aerator according to manufacturer’s instructions (see annexes!).- Function control of the operation-critical mechanical, electro-technical and other componentsof the plant such as the aerator, lift, control unit, valves, alarm unit and the battery of the poweroutage detection device,- Checking the sludge height in the sludge storage; if required, the sludge removal must beprovided for by the operator (for instructions, see section 0),- Performing general cleaning work, e.g. removal of deposits,- Checking the state of repair of the plant,- Checking sufficient ventilation and exhaustion,- Examinations in the aeration tank:• Even ventilation picture (bubble picture),• Oxygen concentration (O 2 /l > 2 mg); if required, adjustment of the operating times of thecompressor,• Sludge volume fraction (< 400 ml/l). If the sludge volume is below 100 ml/l or above 400 ml/l, the duration of the sludgeextraction must be changed in consultation with KLARO GmbH.- Samples from the outlet and analysis of the following values:For each maintenance:- Temperature of the wastewater,- Settleable solids,- pH value,- Odour,- Colour,- Visibility depth,- COD value,- NH4-N (when required),- N inorg (when required),P (when required).1 Specialised companies are operator-independent companies whose employees (skilled personnel)have, due to their professional training and participation in relevant qualification measures, thequalification required for the operation and maintenance of small wastewater treatment plants.KLARO GmbH 31

Operating Manual for SBR small wastewater treatment systemsAny performed maintenance work as well as any detected damage or repair work carried out and furtheraction must be summarised in a maintenance report by the maintenance company. The corresponding formcan be found in the annex. The findings of the examinations must also be recorded in the maintenancereport. The maintenance report must be handed over to the operator of the plant so that this report can besubmitted to the competent authority after having been requested to do so. The maintenance report must beattached to the operating instructions. Please keep the operation log easily accessible. Note: Breakdowns of the plant due to inadequate maintenance (e.g. of the compressor) exclude freereplacement within the scope of warranty.7.3. Operating instructionsAs a matter of principle, only substances that, due to their nature, correspond to domestic untreatedwastewater may be supplied to the plant for treatment.Biocides, toxic or biologically incompatible or non-degradable substances must not enter the plant, sincethey cause biological process problems. In particular, the following substances must not be discharged:- Rainwater from roof surfaces and courtyard areas,- Infiltration water (e.g. drainage water),- Residues arising from animal farming in solid and liquid form,- Commercial or agricultural untreated wastewater provided that it cannot be compared withdomestic untreated wastewater,- Chemicals, pharmaceuticals, mineral oils, solvents,- Cooling water,- Coarse substances in the form of leftovers, plastics and sanitary products, coffee filter bags,bottle lids and other household items,- Milk and dairy products,- Discharge water from swimming pools,- Larger quantities of blood.If larger quantities of fats or vegetable oils accumulate, it is recommended to pre-clean the fat-containingwastewater in a fat separator that is installed upstream to the wastewater treatment plant (Caution:Faeces must not be discharged into the fat separator!).In the table below, individual substances that must not be disposed of using the wastewater treatmentplant are listed once more in more detail:Solid or liquid substances thatmust not be disposed of usingWhat damage they do:Where they are adequatelydisposed of:the drain and/or toilet:Adhesive plaster Clogs the pipes DustbinAsh Does not decompose DustbinBird sand, cat litterCauses deposits and clogging of the DustbinpipesBrush cleaners Poison the wastewater Collection point of theadministrative districtCat litter Clogs the pipes DustbinCement water Settles, concretes Hire specialist company32KLARO GmbH

Operating Manual for SBR small wastewater treatment systems4. Installation (Septic Tank Application)1. Installation site selection19Install our blower near the septic tank.If the pipeline is long, the sewage treatment may not perform well due to an insufficient airflow.Install in a place which is convenient for maintenance.Don , t install over a manhole or on soft ground.Avoid areas where wind-blown leaves and dust gathers.Install in a well ventilated place.Install at least 30cm away from the wall of a house.Installation in the shade is recommended to suppress heat generation of the blower.,Don t install the blower where it will be flooded with water. Make sure that the blower isinstalled over the water level ot the sewage tank/aquarium to avoid any backflow of the water.If the blower is installed under the water level a backflow valve must be used.Don , t install where there is excess moisture or humidity.2. Method of Installation12910234567834567811The base should be made of concrete strong enough to bear the weight and block vibration fromthe blower.The base should be at least 10cm above the ground level and 5cm larger than the externaldimensions of the blower.Provide a separate power outlet to be only used for the blower.Electrical work must be done by a qualified electrician.The power supply should be the rated voltage shown on the label on the blower and be fitted withan earth leakage breaker and over-current breaker.The power outlet used should be waterproof and include an earth connected to ground.Place the blower horizontally on the base.A soft rubber hose must be used for connection between the air outlet of the blower and the pipe.The rubber hose must be fastened with hose clamps.When making the connection, level the air outlet and the pipe to ensure the hose is not kinked orblocked.Before starting the operation of the blower, ensure that the water level in the septic tank isappropriate and the valves on the pipeline are properly opened.3. Start operationInsert the power plug into the power outlet with full contact so that the plug itself does not wobble.Incomplete connection may cause an electric shock or a fire.After starting operation ensure that there is;No air leakage from the hose and the pipe connection.No abnormal noise from the blower.No vibration transmitted to the ground due to strained piping.Water levelHoseHose clampBlowerBaseAir outlet of BlowerHoseHose clampOver Current BreakerEarth Leakage BreakerPower Distribution LineWaterproof PowerOutlet with groundingBlowerWater tank or PondAerobic SewageTreatment TankBase45.

L1L2L1 L2 L3L3Operating Manual for SBR small wastewater treatment systems13.2. Becker and Rietschle rotary slide compressorsNote:The Becker rotary slide compressors used by us are equipped with a pressure control valve that is factorypre-set to a maximum pressure of 0.5 bar.With our plants, an operating pressure of < 0.3 bar is common. If a pressure of > 0.5 bar (e.g. due to a bentair hose) occurs at the plant, a part of the air is blown off via the pressure control valve. Thus, thecompressor is protected against damage or excessive wear and tear.1.Warning NoticeHigh VoltageOnly qualified staff maywork on electroniccomponentsHigh Voltageaccording to ANSIAmerican, NationalStandardsInstituteQualified StaffMarked operations mayonly be executed byqualified electriciansAutomatic Start-UpWhen servicing thedevice must be turned offHot Surfacewill cause burns.Let device cool downbefore maintenanceNoteIgnoring notices willcause severe damage tothe pump2.InterdictionOilPump works without oilAvoid absorption of oilfumesMarked areasmay not be subject toweightLiquidsmay not be conveyedExplosive substancesmay not be conveyedFlammable Substancesmay not be conveyedToxic Substancesmay not be conveyedAssemblyIncorrect fitting position3.RulesWear protective gogglesWear protective glovesWear protective earmuffsSound level informatione.g. 85 dB (A)4.AdviceActive principleRotary vane pumpOnly air may be conveyedAIRActive principleside channel fan only airmay be conveyedMaintenanceRegularly execute themarked proceduresStoring / AssemblyProtect pump fromhumiditymax.800mAssemblyCharacteristic data isvalid up to 800m abovesea leveli +Further Information(optional Data)- name plate- Internet-pSpecificationVacuum pump+pSpecificationCompressorSafety valveVACUUMPRESSUREFactory-made Revolvingfield clockwise aspre-requisite for pumpattachment50/60 Hz =OFF=ONSwitch intervalNot more than10x per hourL2 L1 L3I > I > I >U1 V1 W1M 3Arrange Motor-circuitswitchBlow out marked areaswith air pressure3000 hMaintenance intervalObserve minimum gatevalve measurementevery 3.000 hoursFilter MaintenanceService according to dustaccumulation exchangeold cartridge dispose oldwww.becker-international.com60KLARO GmbH
