An installation for sewer water biological comprises hydraulically-linked a two-staged aeration tank, a reservoir to purify flow equipped with cartridge filters, and channels to feed processing and discharge treated water. The aeration tank, with two hydraulically-linked compartments, also includes a degassing chamber separated by an inclined partition from the second compartment (stage) of the aeration tank, and a stabilization chamber with built-in aeration system.

In the second modification of the design, purification tank filters are additionally equipped with a below-installed regeneration system.
