High Oxygen Transfer Efficiency: EPDM/Silicone microporous membrane ensures efficient oxygen dissolution for biological treatment.
Anti-Blocking Micro-Holes: Micro-holes automatically expand with air intake and close when off, preventing blockage without special filtration.
Reverse Folding Structure: Prevents membrane detachment and improves sealing integrity during operation.
Non-Return Design: Thick, unperforated center blocks liquid backflow into the pipeline when air supply stops.
Durable EPDM Material: Resistant to aging, corrosion, acids, and alkalis for long-term industrial use.
Fine Bubble Technology: Generates 1-6mm bubbles to reduce shear stress on sludge particles.
Vibration-Resistant Connector: Stronger connection between diffuser disc and air pipeline prevents loosening from vibration.
Customizable Options: Available in EPDM or Silicone materials, Black or Blue colors, with full customization support.

Product Q&A
Q:What is the main function of the aeration disc?
A:
It provides oxygenation by dissolving air into water for aerobic microorganisms and mixes sludge, wastewater, and air thoroughly for uniform contact.
Q:What is the lifespan of an aeration disc?
A:
Under normal conditions, EPDM membranes last 5-8 years. Silicone membranes may last longer. Lifespan depends on water quality, maintenance, and air quality.
Q:What are the differences between EPDM and silicone membranes?
A:
EPDM is cost-effective and resists municipal wastewater chemicals but not oils. Silicone resists oils/hydrocarbons, is more flexible, and resists aging better, but is more expensive.
Q:How does the diffuser prevent pipeline blockage?
A:
The micro-holes automatically close when no air is supplied, preventing mixture backflow. No special air filtration is needed, and intermittent supply does not cause blockage.
Q:What materials are used in the diffuser construction?
A:
The main body is made of ABS engineering plastic, covered with a special rubber EPDM or silicone microporous membrane.
