Product Description

Disc Air Diffuser for Oxygen Supply Equipment in Sewage Bio-Treatment Process

Color of the frame and baseboard: gray or white
Size of the disc aerator: 215mm, 270mm, 330mm


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*104
Resilience % >45
