PLANT AND METHOD OF CONCENTRATION OF POLLUTANTS IN WASTE WATER Russian patent published in 2016 - IPC C02F1/04 B01D1/14 

FIELD: construction.

SUBSTANCE: invention relates to waste water treatment using a plant that consumes thermal energy produced from direct burning of hydrocarbon fuel and/or by means of usage of thermal energy of spend gases produced from burning of hydrocarbons in engines. An evaporation plant for concentration of pollutants in untreated water comprises an evaporator 110 of untreated water, including a flue connected to a source of hot gas; a system of distribution of untreated water inside the flue with increase of its surface area; a control system including at least one control station for monitoring of temperature inside the flue and at least one pump to control a flow of untreated water sent into a system of distribution of untreated water; and a system of collection connected to the flue for water collection with concentrated pollutants from the flue.

EFFECT: invention makes it possible to reduce quantity of pollutants in spent gases, which may be released into atmosphere, and to reduce the total volume of polluted waste water.
