Product Description

EPDM oxygen fine bubble disc diffuser in water treatment rubber membrane air diffuser

bubble disc diffuser for wastewater treatment features a unique split pattern and slit shapes, which can disperse air bubbles in an extremely fine and uniform pattern for high oxygen transfer efficiency. A much highly effective and integrated check valve enables the aeration zones to be easily shut down for air-on/air-off applications. It can be operated over a wide range of airflows with minimum maintenance for long term performance.

Bubble diffuser features:
1.The rubber washer and the corresponding groove are designed to ensure the air tightness of the product. Instead of using raw tape in the installation process, it is convenient to install, stable and reliable.

2.Check valve structure. When operation stops, the membrane covers the structure under the action of rebound force and water depth pressure to prevent the backflow of mud water.
3.Mechanical assembly production line, hot welding instead of adhesive process, to ensure adequate supply, uniform productquality, stable and reliable.
4.The spanner position is designed. Spanner is used to replace the traditional hand-twist installation, avoid membrane damage. And installation is convenient and reliable.

5.Product adopts single-ear pole clamp which make product bear 360 degree uniform stress. Under heat expansion and contraction as well as vibration, it can play a spring regulating effect. All single-ear clamps are 316
stainless steel material. It is more reliable in sewage.

6.Six channel design, increase ventilation cross - sectional area, reduce resistance, efficient and energy - saving. The multiple positions of the membrane jointly bear air friction, reduce local wear and extend aerator membrane service life. Also, promote product 360 ° aeration, improve the product efficiency.
 

Bubble diffuser application:
1.Aeration of fishpond and other applications
2.Aeration of deep aeration basin
3.Aeration for excreta and animal waste water treatment plant
4.Aeration for denitrification/dephosphorization aerobic processes
5.Aeration for high concentration waste water aeration basin,and aeration for regulating pond of waste water treatment plant
6.Aeration for SBR,MBBR reaction basin,contact oxidation pond;activated sludge aeration basin in sewage disposal plant
