WATER PURIFICATION TREATMENT PLANT WITH PULSED FLUSHING OF GRANULAR LOADING Russian patent published in 2018 - IPC B01D24/46 

FIELD: technology of water and air purification.

SUBSTANCE: invention refers to the field of water purification and can be used in order to purify natural waters on filters with granular loading for domestic, drinking, industrial and agricultural water supply, as well as for sewage treatment. Water purification treatment plant with pulsed flushing of granular loading comprises at least one granular loading filter, upper and lower switchgears, pipelines for supplying water for cleaning, supplying rinsing water with the bend and pipelines for withdrawal of filtrate and washing water, locking devices with the drives that are installed on the water supply pipelines for cleaning, supply of washing water and withdrawal of filtrate, the filter operation control unit, and the pulsed water flushing generation unit with granular loading, which is installed at the bend of the flushing water supply pipeline and contains the pressure accumulator with the pressure switch, the pressure gauge and the switching module. Control unit is connected to the pulsed water flushing generation unit with granular loading and to the drives of the locking devices.

EFFECT: increased degree of regeneration of the filtering loading while reducing the flow of water for flushing.
