Product Description

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 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.

EPDM rubber membrane performance parameters are tabulated below:

Item	Unit	Value
Hardness (Shore A)		55-60/85-87
Tensile strength	Mpa	17
Tear breakage elongation, min.	%	>650
Tear strength	N/m	>1.7*10^4
Resilience	%	>45
