Diffusers and Accessories


The fine bubble membrane diffuser disk is easy and simple installation for wastewater treatment system. It can generate a lot of very small bubbles from the holes drilled at air diffuser disc. Plenty of small bubbles can generate sufficient oxgen transfer which can help the bacterial to produce enzymes and then break down the waste, so it can be filtered by membranes. Furthermore, the high oxygen transfer rate efficiency can save your energy cost and prevent clogging when the air pump is not operating.
