Application Scope
Fine 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.

Material Property
EPDM 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.
