Activated sludge tank at Beckton sewage treatment plant, UK.The white bubbles are due to the diffused air aeration system. The activated sludge process is a type of biological wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa.

The diffusers can be suspended slightly above the lagoon floor or may rest on the bottom. Flexible airline or weighted air hose supplies air to the diffuser unit from the air lateral (either floating or submerged). [7]
Nonpoint sources are the most significant single source of water pollution in the United States, accounting for almost half of all water pollution, [1] and agricultural runoff is the single largest source of nonpoint source water pollution. [2] This water pollution has a number of detrimental effects on human health and the environment.
