How it works
The variable microporous aerator opens its membrane micropores under air pressure for uniform aeration and closes them under water pressure when supply stops, preventing blockage. Gas enters the branch pipe from the main intake, passes through the connector into the gap between the aeration membrane tube and the reinforcing liner, and the micropores open under air pressure.
Where it is used
It suits municipal and industrial wastewater aeration basins, with high oxygen transfer efficiency, long service life, simple and quick installation, low cost, a large service area and a negative-pressure design.
Installation modes
Three modes: traditional, laid at the bottom of the dried tank in rings; hanging, with the inlet branch on the surface and the pipe suspended, so maintenance needs no draining and air control is easy; and platform, where several pipes are assembled into a ring platform that sinks for aeration and floats for maintenance.
Frequently asked questions
Q: How does the aerator keep water out of the membrane when the air stops? A: The micropores open under air pressure and close under water pressure when the supply stops, which is what prevents blockage.
Q: What path does the air take inside the aerator? A: From the main intake into the branch pipe, through the connector into the gap between the aeration membrane tube and the reinforcing liner, where the micropores open under pressure.
Q: Which installation mode can be serviced without draining the tank? A: The hanging mode: the inlet branch stays on the surface and the pipe is suspended, so maintenance needs no draining and air control is easy.
Q: What is the platform mode? A: Several pipes are assembled into a ring platform that sinks for aeration and floats back up for maintenance.
Q: Where is the variable microporous aerator used? A: Municipal and industrial wastewater aeration basins, where its case rests on high oxygen transfer efficiency, long service life, quick installation, low cost, a large service area and a negative-pressure design.
