The variable microporous aerator

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. It suits municipal and industrial wastewater aeration basins with high oxygen transfer efficiency, long life, quick installation, low cost, large service area and negative-pressure design. Installation modes: traditional bottom ring layout; hanging layout (maintenance without draining, easy air control); and ring-platform layout that sinks for aeration and floats for maintenance.
