The membrane is fixed tothis body with a plastic frame also made of glass reinforced Polypropylene.®Standard membranes are made of SUPRAFORM (EPDM).® ®Membranes made of SUPRASIL (Silicone) and SUPRADUR (Polyurethane) are also available.The membranes have a unique slot-arrangment. The size and arrangement of those slots isoptimized to archieve maximum oxygen transfer efficiency.CHARACTERISTICS®OXYFLEX -MF membrane plate diffusers have low pressure loss.®OXYFLEX -MF membrane plate diffusers are highly resitant against soiling.®OXYFLEX -MF membrane plate diffusers produce fine bubbles of a medium diameter < 2 mm.Unlike tube diffusers, the whole active diffuser surface is at the same hydraulic level, therefore themembranes operate evenly across the full range from minimal to maximal air flow. The featureresults in optimum lifetime and efficiency.®OXYFLEX -MF membrane plate diffusers can be operated intermittently.®OXYFLEX -MF membrane plate diffusers can be installed with plastic- and/or stainless steel pipesand are used for all geometric forms of tanks, but they are extraordinarily good for medium and hugesized tanks.PERFORMANCE®OXYFLEX -MF membrane plate diffusers are well established and are working to the clientssatisfaction world-wide.® ® 3OXYFLEX -MF membrane plate diffusers have a very wide range, OXYFLEX -MF 650: 0-13Nm /h.® 3The design air flow should be approximately, OXYFLEX -MF 650: 7 ± 2 Nm /h®OXYFLEX -MF membrane plate diffusers can reach specific oxygen transfer efficiency up to 253gO /Nm xm , if coverage and water depth is favourable.2 supCOMBINATIONVARIATIONS®For plants with partly intermittent operated tanks, OXYFLEX -MF membrane plate diffusers can be®combined with BRANDOL ceramic tube diffusers. However, different pressure losses have to beconsidered.®Modifed OXYFLEX -MF membrane plate diffusers are also available for drinking water purposes.®OXYFLEX -MF membrane plate diffusers are also available as coarse bubble diffusers.Supratec ® von-Drais-Straße 7 • D-55469 Simmern • Fon: +49 (0 67 61) 9 60 60 • Fax: +49 (0 67 61) 970 774 • info@supratec.cc

DIN 7716 has to beconsidered.®Before installation of the OXYFLEX -MF 650 - membrane plate diffuser Type ‘AS’ it has to bechecked that the piping system is clean.Drilling chips, dirt etc. have to be removed, as those will be transported into the diffusers as soon asblowers are set into operation causing serious damage to the diffuser membranes.LEVELLINGINSTALLATION®OXYFLEX -MF 650 - membrane plate diffuser Type ‘AS’ normallyinstalled onto round pipes. The piping system has to be levelled to maximum ± 10 mm.®OXYFLEX -MF 650 - membrane plate diffuser Type ‘AS’ can be fixed to round pipes made ofstainless steel or plastic, with a minimum diameter of 50 mm. On the upper side of those pipes,centred holes of diameter Ø 14 mm must be made.The clamp will be installed in such a way, that the hole of Ø 14 mm and the opening of the clamp arealigned.Care must be taken of the horizontal seat of the diffusers. The O-Ring seal, made of EPDM must beclean and undamaged and should sit between diffuser and pipe.Supratec ® von-Drais-Straße 7 • D-55469 Simmern • Fon: +49 (0 67 61) 9 60 60 • Fax: +49 (0 67 61) 970 774 • info@supratec.cc

It is necessary to have a precise air-flowmeasurement system.®After successful oxygen transfer efficiency test, start up of the OXYFLEX -MF 650 membrane platediffusers may follow immediately. If there is a postponement of the start up, care should be taken that®the water level stays at least 100 cm above diffusers’ surface to protect OXYFLEX -MF 650membrane plate diffusers from sunlight and / or freezing.Supratec ® von-Drais-Straße 7 • D-55469 Simmern • Fon: +49 (0 67 61) 9 60 60 • Fax: +49 (0 67 61) 970 774 • info@supratec.cc

Usually it is enoughto have one run of 10 to 15 minutes operation at minimum air-flow per day, where each single® 3OXYFLEX -MF 650 membrane plate diffuser shall operate at a specific air-flow of at least 10 Nm /hper unit.To do so, it may help to shut down the system partially, by closing the corresponding valves.This removes layers of sludge which may have occurred after long times of in operation of thesystem or long times of low specific air flow.®At least once per year OXYFLEX - MF 650 membrane plate diffusers should be checked visually,particulary they should be checked for layers of sludge or similar. If so, those layers should beremoved carefully.A seperate maintenance-contract is available.SUPERVISIONA Visual bubble check should be carried out daily. The pressure loss of the system should bemonitored and reported monthly.Apparent changes of the bubble distribution and/or of the pressure loss should be promptly reported®to SUPRATEC GmbH, especially at installations with intermittent operation where there is a risk that®activated sludge could penetrate the entire piping through a damaged OXYFLEX -MF 650®membrane plate diffuser which would affect function and lifetime of all OXYFLEX -MF 650membrane plate diffusers in the system.® ®The maximum of SUPRATEC GmbH’s warranty for OXYFLEX -MF 650 membrane is 24 months.Longer warranty can be arranged only with conclusion of a maintenance contract between the®operator and SUPRATEC GmbH.Damage and/or other influences are specifically excluded from the warranty promise.WARRANTYThe warranty ends if it is known, that sewage is partially or mainly of industrial origin and/or the®sewage has a damaging influence on membrane diffusers and SUPRATEC GmbH was not informedaccordingly.®In such a case, a confirmation of the warranty is to be ordered through SUPRATEC GmbH.®The general sales and warranty conditions of SUPRATEC GmbH apply.Supratec ® von-Drais-Straße 7 • D-55469 Simmern • Fon: +49 (0 67 61) 9 60 60 • Fax: +49 (0 67 61) 970 774 • info@supratec.cc
