Membrane tube diffuser
The membrane tube diffuser is a new type of oxygenation aerator and the core equipment of A/O process (activated sludge biochemistry technology). It can be applied to every position of the sewage pool. It is featured by easy and convenient installation and maintenance, even oxygenation and low energy consumption. Flexible, easy and convenient installation. It can be installed during normal operation, not necessary to drain water. Simple maintenance.
Membrane Tube Bubble Diffuser can be connected on one side or in pairs to different rectangular and round tubes (ABS material) with the appropriate adapter. The membranes are manufactured with premium quality EPDM material and are available with fine or coarse-bubble perforation. The support tubes(ABS or PVC material)can be reused when membranes are replaced.
