SSI ECD215 Disc Diffuser System – Advanced Aeration for Biological Wastewater Treatment

In contemporary wastewater treatment processes, diffusers are extensively utilized as critical components that significantly impact plant operational efficiency and effluent quality. Conventional disc diffusers typically employ flat rubber membranes secured against either planar or slightly convex support plates using compression covers. These legacy systems rely solely on the rubber's intrinsic elasticity for membrane expansion during aeration, resulting in concentrated stress distribution at both central and peripheral zones. This design limitation leads to:

Restricted membrane displacement

Elevated aeration resistance

Accelerated membrane aging/tearing

Diminished oxygen transfer efficiency

Increased power consumption

Frequent maintenance requirements

To address these inherent drawbacks, our R&D team has developed a next-generation rubber membrane disc diffuser through years of technological innovation.
