METHOD OF WATER TREATMENT Russian patent published in 2014 - IPC C02F9/04 C02F1/28 C02F1/52 

FIELD: process engineering.

SUBSTANCE: invention relates to treatment of contaminated water. This method comprises bringing of water in contact with at least one adsorbent powder in zone (2) of preliminary interaction with mixing. Then, follow flocculation with weighted flakes and deposition. Mix of sediment, ballast and adsorbent powder is removed from sedimentation zone bottom (5). Said mix is fed into hydraulic cyclone (11) to displace hydrocyclone (11) top product containing the mix of sediment and adsorbent powder into transition zone (14). Mix of sediment and adsorbent powder are returned from transition zone (14) to zone (2) of preliminary interaction. Process incorporates the step whereat at least one index of adsorbent powder in preliminary interaction zone (2) is obtained. Suspension of green adsorbent powder in water is fed upstream of zone (2) when concentration of said powder in this zone is lower than preset threshold value and the step of acidification of said sorbent.

EFFECT: production of water suitable for drinking.
