Operating Manual - KLARO 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
