FIELD: petroleum refining industry; separation of oil-water emulsions and purification of water. ^ SUBSTANCE: the invention is dealt with a field of separation of oil-water emulsions and purification of water, in particular, with installations used for purification of industrial, natural and waste waters from petroleum, oil products and mechanical impurities and for separation into the component materials of the stable emulsions. The installation contains: a cage; a vertical filtering member of a cartridge type with a cover, a bottom and a grid mounted between them; a central perforated pipe and a coaxially placed fibrous filtering material; a cavity for collection of the lubricated product and branch-pipes for feeding of an emulsion and a withdrawal of products of separation. The first on a course of a divided emulsion running layer of the filtering material is made out of a hydrophobic polymeric fiber in the form of a non-woven linen of a volumetric corrugated structure, and the second is made out of a hydrophilic superfine basalt fibers. Ribs of the volumetric corrugated structure of the first layer are oriented along the central pipe and the cavity for collection of the lubricated product is placed under the cover of the filtering member. The invention allows to conduct efficiently agglomeration and separation of the finely dispersed particles of oil products at the stage of purification up to the level of maximum permissible concentration (MPC) and also from industrial waters and waste waters. ^ EFFECT: the invention allows efficiently agglomerate and separate finely dispersed particles of oil products at purification process up to MPC level and to clean industrial and waste waters. ^ 5 cl, 2 dwg, 1 tbl |
