FIELD: process engineering.
SUBSTANCE: invention relates to oil and gas production, particularly, to treatment of bottom waters generated at oil processing stations. Proposed method consists in feeding the water to be cleaned via ejector arranged at flotation chamber bottom whereto sediment from flotation chamber flows continuously. Inclined partition is arranged inside the tank, its bottom side being arranged nearby ejector inlet and its top side at tank wall opposite the ejector. Ejector outlet is connected with aforesaid flow shaping partition that directs water flow asymmetrically about tank axis.
EFFECT: high-efficiency continuous bottom water treatment.
