Diameter 330mm Fine Bubble Disc Aerator, Aeration System Equipment for Wastewater Treatment

Application ScopeFine bubble aerator system is designed exclusively for oxygen supply in sewage bio-treatment process. As its aerator membrane adopts EPDM rubber, which has corrosion resistance, aging resistance and service life unparallel by other engineering composite rubbers, thus it is widely applied in urban domestic sewage treatment system and industrial sewage treatment plants. This system can be used both for continuous running system and for batch running system.Material of membrane: we have EPDM and Silicone rubber for your choice.If used in special waste water, please provide detailed water composition specification for our technical staff to analyze and confirmation prior to use.  Product Show  Material PropertyEPDM rubber does not contain plasticizer, can eternally keep elasticity, not easily cakes and ages, does not get brittle, with robust resistance to high temperature, low temperature, oils and corrosion; its service life is much longer than any other composite rubbers.EPDM rubber membrane performance parameters are tabulated below:ItemUnitValueHardness (Shore A) 55-60/85-87Tensile strengthMpa17Tear breakage elongation, min.%>650Tear strengthN/m>1.7*104Resilience%>45    Structure   Application Show      Parameters ModePR-D330(12")Material of MembraneEPDMSilicone rubberThickness of membrane2.0mm±0.1mm2.0mm±0.1mmEffective diffusion area0.070m20.070m2Openings/pcabout 10000 openingsabout 10000 openingsDiameter of bubble0.8mm-1.5mm1.0mm-1.8mmLifetime of membrane>6yrs>6yrsStandard volume of aeration4.0m³/h-6.0m³/h4.0m³/h-6.0m³/hAeration range2.5m³/h-10m³/h2.5m³/h-10m³/hResistance loss2.0kPa-4.2kPa2.0kPa-4.0kPaStandard oxygen transfer rate(depth of water:6m)≥38%≥37%Standard oxygenation capacity≥0.55kgO2/h≥0.52kgO2/hTheoretical power efficiency≥8.9kgO2/kw.h≥8.8kgO2/kw.hService aera0.4m2/pc-1.5m2/pc0.4m2/pc-1.5m2/pcTest was made under standard condition, i.e., clean, oxygen-free water (20ºC), air pressure is 1.013*105   Packing/Component Info   ModelPR-D215PR-D270PR-330Weight/Set0.49kg0.68kg0.96kgWeight/Carton17.5kg18.5kg24kgPcs/Carton342624Ball Check ValveNonNonFor DN80 PipeMaterial of Support BaseReinforced PPReinforced PPABSOuter Diameter of The Support Base225270330Specification of Connection PartDN20 Screw Connector Pipes Applied ToDN50~DN100HolderWedged HolderMaterial of HolderABSOther Products    Company ShowCertificatesExhibitionsWKAER is a trade mark we registered in China mainland.
