METHOD OF PURIFYING WATER FROM OIL PRODUCTS BY MEANS OF MAGNETIC FLUID AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2016 - IPC C02F1/48 C02F1/40 

FIELD: ecology.

SUBSTANCE: invention relates to methods of purifying water medium from oil products by providing magnetic properties for the oil products and can be used for waste water purification in all industries and in case of man-made disasters. Method of purifying water from oil products, consisting in coalescence of dispersed phase by passing a stream of water with oil products through a layer of oleophilic coalescing material followed by separation of oil products, coalescence of dispersed phase is carried out simultaneously with its magnetization. Magnetic fluid on related basis to the separated oil product is used as a coalescing material, as which kerosene or liquid derivative of oil production is used, covering with a layer the ferromagnetic material with developed surface, magnetized by external magnetic field. Separation of the magnetized oil product from ferromagnetic material is carried out in gradient magnetic field. Housing 1 of the device for water purification from oil products in cross section has a shape of symmetrical trapezium with smaller top base. End walls 8, bottom 9, housing cover 10 and horizontal partition 2 are made of nonmagnetic material, and side walls 11 are made of magnetic material and extend below the bottom of the housing, under which there are permanent magnets 12 adjoining by like poles to the side walls claws.

EFFECT: technical result consists in increase of efficiency of water purification and improved quality of collected oil products.
