An ultrafiltration unit is installed in the housing along its axis, the outlet of which is connected to the filtrate outlet. In the case there is a floating loading. 2 Il.

Description

The invention relates to the purification of water and the concentration of a precipitate by filtration through ultrafiltration and reverse osmosis membranes.

The purpose of the invention is to improve the performance of the filtrate.

FIG. 1 shows an apparatus for cleaning a liquid, a general view; in fig. 2 - ultrafiltration unit.

In the housing 1, having a cylindrical 2 and a conical 3 parts, supply pipes for supplying raw water 4, drainage of filtrate 5 and concentrate 6, an ultrafiltration unit 7 is installed in the axis in cylindrical part 2 of –Elements 8 circumference of the body surface. In the cavity of the housing 1 a floating load is placed from a material whose density is less than the density of water, for example, from expanded polystyrene. Element 8 contains a grid 9, a substrate 10 and a membrane 11, which are mounted with each other “

filtrate water.JJ,

The initial water supplied under pressure into the casing 1, pre-filled with water, through the source water supply pipe 4 is twisted in the cylindrical part 2 of the casing 1. As a result of centrifugal force, the suspension separates, concentrates in the sediment in the conical part 3 of the casing and it is then discharged from the housing through the concentrate outlet 6.

The water left in the casing passes through the grids 9 of the substrate 10 and the membrane 11 along radial 13 and 17, central 1C channels to the nozzle 5 of the filtrate outlet. Water is purified when it is filtered through ultrafiltration elements 8. At the same time, they are regenerated due to movement of the floating load between ultrafiltration elements 8 in radial channels 17 and its interaction with contaminated surfaces.

Claims (1)

The effect of increasing the productivity of the filtrate is due to the fact that the filtration process takes place with a smaller thickness of the concentration polarization layer, which is achieved due to the efficient cleaning of the surface of the ultrafiltration unit. A water treatment apparatus comprising a cylindrical body with source water supply nozzles, discharging filtrate and concentrate, on the axis of which an ultrafiltration unit is installed with an outlet channel connected to the filtrate drain nozzle, characterized in that in order to increase the filtrate performance, a floating load in the form of granules from a material with a lower density than the density of water, for example, from foam polystyrene, and the feed pipe of the source water is located tangentially to the circumference of the surface Orpus (made tangentially). source code Phi .2
