D Air is the elastic rubber membrane diffuser disc. It is designed to perform under physical and chemical harsh conditions. The body is made of Polypropylene co-polymer that exhibits great strength under high temperature fluctuations. The membrane is so designed to have long life especially in hot climate environment. It is punctured to more than 5000 minuscule holes, in order to create the very fine bubble. D Air is easily installed and compatible with most pipe connections available in the market.
Energy Saving
By replacing your aeration system from mechanical aerators, you could half your electricity cost. The finer bubble creates high oxygen transfer while gentle enough to promote good sludge floc forming. The high efficiency also results in shorter retention time in aeration tank, thus treatment capacity in increased.
