Product Description

9inch 12 ich Silicone Air Aeration Plate Bubble Diffuser for Sewage Treatment Equipment

Product Description

Fine bubble diffuser is an important equipment for aeration and oxygenation of water supply and drainage, which is suitable for municipal sewage, industrial wastewater and other sewage treatment. The disc microporous fine bubble diffuser is equipped with a check valve, which can prevent the sewage from flowing back when the gas stops; the diaphragm has a long service life, which can be used for 5-8 years; the design is simple, the price is low, and the cost performance is high.

 

Over 6300 perforations in Dn215mm fine bubble diffuser, air deflector diameter is 0.5cm, the contact sapce with membrane is 0.15cm, which make the opening rate of membrane can reach 99.9%. Also improve oxygenation capacity, oxygen utilization rate and reduce ventilation.
