Epdm Diffuser Membrane Fine Bubble Tube Diffuser / Tube Air Diffuser for Water Treatment Plant System
EPDM Fine Bubble Diffuser Tube for Water Treatment Plant System
The wastewater treatment of activated sludge and contact aeration process and aquarium will all need high Oxygen transfer rate or Oxygen transfer efficiency, and low-pressure loss by the membrane. The reinforced EPDM can continuously create a fine bubble from slots on the EPDM membrane of the disc type or tube-type diffuser.
MOC: EPDM
Manufactured by compression molding with a standard cure,low plasticizer content, and 1mm or 2mm
perforations.Compression molding with modern equipment utilizing individual thermocouples and
vacuum technology ensures a repeatable very high quality product.
