The wastewater treatment of activated sludge and contact aeration process and aquarium will all need high Oxygen transfer rate or Oxygen transfer efficiency, and low pressure loss by the membrane. 

The expected duty life may be over five years without tearing or bursting. There are other material selections of self-sink silicon rubber membrane, ceramic diffuser, air stone, and coil looking diffuser. There are also course bubble air diffuser for application of liquid mixture. The diffuser can be used for roots blower, ring blower and linear air pump. The diffuser also has advantage of much energy reduction.

Our Fine Bubble Tube Diffuser can be connected on one side or in pairs to different rectangular and round tubes (ABS material) with the appropriate adapter.The support tubes(ABS or PVC material)can be reused when membranes are replaced.
