Product Description

300mm EPDM Disc Fine Bubble Air Diffuser Oxygen Microbubble Aerator

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.

EPDM Membrane Air Bubble Diffuser Disc Type Aeration Diffuser features:

 

1.High aeration effectiveness The aeration process involves bringing together water and oxygen for oxidation and dissolutions of metals and dissolution of gases. With our fine bubble disc diffuser and fine bubble tube diffuser, it makes the process more effective.
2.High oxygen transfer efficiency (OTE) Fine bubble diffusers generally work to treat water waste through OTE. However, with our products, it helps for a more enhanced process considering its specifications.
3.Energy efficient Fine bubble diffusers have long been introduced opposite the coarse diffusers. One of the feature of our product is its energy saving mechanism.That is, it needs lesser energy for it to work. In effect, you will benefit from energy conservation.
4.System versatility We have fine bubble diffusers that suit to different water waste management systems. These diffusers are manufactured to ensure that it can adapt to different kinds of systems and basins that it yet to be made or are already existing. Thus, if you are replacing or upgrading, you can be catered.
5.Material efficiency Our diffusers are made from various material from ethylene propylene diene monomer rubber (EPDM rubber), which conventional material. We also have fEPDM that has high chemical resistance.
