摘要： The subject of the invention consists in the method for initial regeneration of tannery wastes, comprising the process of filtration, including microfiltration and ultrafiltration, characterised in that the following stages are completed: a) at first raw tannery wastes are subject to initial filtration to eliminate solid suspended matter, then b) the resultant filtrate is subject to microfiltration and the permeate obtained is directed to ultrafilters module where a chromium recirculating mixture is produced or an additional stage is applied d) where the chromium- recirculating mixture is nanofiltered.

摘要： The invention relates to a spacer with mixing elements, particularly for membrane modules. The spacer comprises a three-dimensional net with mesh (1) having the shape of polygons with number of sides n ≥ 5, with at least one pair of sides made of support beams (2) which are not in contact with one another, parallel to one another, preferably inclined from the axis defining the direction of the flow, each of which fits in the volume of a cylinder and is in contact with the surface of membranes (4), with at least one pair of vertices of the sides made of support beams (2) is connected with one another by means of two connectors (3) comprising mixing elements which are not in contact with the surface of both membranes (4) and forming between them an angle β

摘要： The invention relates to a method for selective removal of polycyclic aromatic hydrocarbons from oils obtained as a result of petroleum processing, comprising two separate processes: filtration through a porous carbon-containing bed comprising and filtration through microfiltration membranes. The method is particularly useful for purifying oils selected from unconverted oils obtained in hydrocracking processes, products of further processing of these oils, engine oil and used engine oil.
