Air And Disc Diffusers are considered as integral parts of sewage and effluent treatment procedures.  Ergonomic design of these air bubble diffusers promotes passing of air bubbles into water pipes in order to feed microorganisms present in tanks while processing waste water. These compression molded diffusers are equipped with silicon or EPDM membrane and PP made high temperature proof retaining ring. Water tight O ring seal of their membrane is compressed by the remaining ring securely to prevent leakage of inside air. Excellent oxygen transferring capacity, long working life, smooth bubble aeration rate and high temperature proof design are the key characteristics of this array of disc diffusers.
