SYSTEM OF COMPLEX WATER TREATMENT OF AQUACULTURE POOLS Russian patent published in 2018 - IPC A01K61/00 

FIELD: technology of water and air purification.

SUBSTANCE: system includes sequentially located: separation of primary mechanical water treatment, which is a container filled with separation slats, which are located on the raised floor by sections; separation of biological water treatment in the pseudo-boiling layer, which is a tank filled with bio-loading located on a raised bottom, above which a device for aeration of bio-loading is placed under the bio-loading layer, separation of the secondary fine mechanical water treatment, which is a container filled with separation lamellae with a smaller free lumen, which sections are located above the raised floor. All containers are vertically oriented and have a height 3–5 times larger than the cross-sectional diameter. In each compartment, the raised floor is made in the form of a perforated plate. Under the raised floor there is a compartment free from the equipment for the entry of contaminated water, and at the bottom of each tank there are cone sediment collectors of mechanical contaminants. At the top of each tank are the outlets of purified water, which are made in one level with a vertical accuracy up to ±0.20 m.

EFFECT: system provides an increase in the degree of water purification with an increase in the life of the bio-loading.
