The Membrane Fine Bubble Diffuser is an advanced aeration device designed to efficiently transfer oxygen in wastewater treatment systems. It generates uniform fine bubbles through precision-perforated membranes, enhancing oxygen dissolution and promoting microbial growth.

Product Overview

The diffuser offers high oxygen transfer efficiency (OTE), low energy consumption, and long service life, making it ideal for biological aeration processes.

Working Principle

Compressed air passes through the air distribution system and enters the diffuser. The flexible EPDM or silicone membrane expands under pressure, allowing air to pass through fine perforations to form tiny bubbles. When aeration stops, the membrane closes automatically, preventing backflow and clogging.

Main Components

Diffuser body: ABS or PVC engineering plastic
Membrane: EPDM, silicone, or PTFE-coated
Air inlet: Standard threaded or clamp-type connector
Check valve: Integrated anti-backflow design
Support base: Stainless steel or plastic frame
