ACTIVATED CARBON-BASED WATER FILTER AND METHOD FOR REGENERATION THEREOF Russian patent published in 2013 - IPC C02F1/28 B01J20/34 

FIELD: chemistry.

SUBSTANCE: activated carbon-based water filter has a housing 4 with an inlet for the water to be treated 1 and an outlet for treated water 2, as well as filter backwashing pipes 6 and units for controlling water supply in treatment and backwashing mode. An inductor 9 is mounted on the inner wall of the housing, said inductor being in form of an inductance coil connected to a high-frequency current generator 10, wherein the outer surface of the housing is heat-insulated. The filter regeneration method involves contactless heating of activated carbon in a high-frequency electromagnetic field.

EFFECT: invention enables to restore sorption capacity of activated carbon without removal and reloading thereof, which makes easier its maintenance and lowers the cost of treating water by automating processes of monitoring and controlling operation of the filter and reducing consumption of activated carbon six- to eight-fold.
