ABS Fine Bubble Membrane Diffuser PTFE Coated EPDM Bubble Disc Diffuser
Membrane Fine Bubble Diffuser
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
Features
  • Fine bubble diameter (1-3 mm) for excellent oxygen transfer
  • High OTE and low system backpressure
  • Corrosion-resistant and anti-aging materials
  • Self-closing membrane prevents clogging and backflow
  • Easy installation and low maintenance
  • Available in disc (Φ215-Φ350 mm) or tube (Φ65×1000 mm) types
Applications
  • Municipal and industrial wastewater treatment
  • Biological aeration tanks (SBR, MBBR, A/O, A²/O)
  • Equalization and oxidation ditches
  • Aerobic and nitrification systems
Optional Configurations
  • Membrane material: EPDM, silicone, or PTFE
  • Type: Disc, tube, or plate diffuser
  • Mounting system: Fixed frame or quick-release
  • Air flow range: 1-12 m³/h per unit
  • Custom connectors and pipeline sizes
