(54) FILTER FOR WATER TREATMENT (57) The invention relates to filters for cleaning water from mechanical impurities with a floating granular load and allows to increase the filter performance while maintaining the quality of water treatment. The water purification filter contains a variable volume chamber 5 placed in the housing 1 under a layer of floating granular load 2, connected to a compressed air source and to a collecting system 4. 1 sludge.

The invention relates to devices for purifying water from mechanical impurities, namely, h filters with a floating granular load, and can be used for purifying drinking water and for purifying industrial effluents.

The purpose of the invention is to increase the filter performance.

The drawing shows schematically the proposed filter for water purification.

The water purification filter consists of a cylindrical body 1 in which a layer of floating granular load 2 is placed, distribution system 3, assembly system 4, variable volume chamber 5 connected by pipeline 6 with a source of compressed air (not shown) and process pipeline 7 with assembly system 4, the pipeline 8 for removal of wash water and air plunger 9.

The filter for water purification works as follows.

Initially, the hydraulic layer of the floating granular load 2 layer was hydraulically sorted, for which water is supplied through the distribution system 3 with an intensity that weights the floating granular load layer 2. elastic material, for example, of rubber, which presses the layer of floating granular load 2 below and ensures the specified porosity of granular load in throughout the filtration cycle. The purified water is poured into the distribution system 3 and then the water is filtered in a layer of floating granular load 2 h. The purified from mechanical impurities in the modular system 4 is discharged to the consumer. When the maximum pressure drop is reached, the flow of purified water is stopped and the filter is set to flush.

The filter was washed with water to be cleaned. To do this, the air from the chamber 5 of variable volume through the process line 7 is fed to the collecting system 4, then to the upper part of the housing 1 and loosened
