Aerators for the oxidation of dissolved iron and hydrogen sulfide, or for volatile gas stripping (VOCs, ammonia).

Diffused aeration systems for biological wastewater treatment include course and fine bubble. Materials of construction can be ceramic or membrane and can be easily installed in new basins or as replacement.

Pond Aeration Systems add air to ponds lakes and fountains, increasing dissolved oxygen content and supplying micro-organisms with oxygen. Compare lake, lagoon and pond aeration systems.
