Fine Bubble EPDM Aeration Disc Diffuser for Biological Processing Tanks

Oxygenation: This process efficiently dissolves oxygen from the air into the water, providing the necessary oxygen for the aerobic microorganisms treating the wastewater. Mixing: The rising water flow generated by releasing air bubbles thoroughly mixes the sludge, wastewater, and air within the tank, ensuring uniform contact between microorganisms and pollutants.

Under normal urban wastewater conditions, the lifespan of a high-quality EPDM membrane is typically 5-8 years. Silica gel membranes may have an even longer lifespan. Lifespan is significantly affected by factors such as water quality, operating time, frequency of cleaning and maintenance, and air quality (including whether it contains oil).

PDM membranes: Advantages: Good resistance to common chemicals in municipal wastewater (such as acids, alkalis, and alcohols); high cost-effectiveness; the first choice for municipal wastewater treatment. Disadvantages: Not resistant to mineral oils and hydrocarbons. Silicone membranes: Advantages: Excellent resistance to oils and hydrocarbons; more flexible; less prone to aging. Disadvantages: Higher price; mainly used for industrial wastewater (such as oily wastewater and food processing waste

No, the incoming air does not need special filtration. The design ensures that intermittent supply of air does not block the holes and pipes.

The main body is made of ABS engineering plastics, and the membrane is covered with special rubber EPDM or silicone microporous membrane.
