Activated sludge system definition

Activated sludge system means a biological wastewater treatment process in which a mixture of wastewater and sludge floc, produced in a raw or settled wastewater by the growth of microorganisms, is agitated and aerated in the presence of a sufficient concentration of dissolved oxygen, followed by sedimentation. Examples include, but are not limited to, conventional activated sludge systems, extended aeration activated sludge systems, oxidation ditches, and sequencing batch reactors.
