FIELD: chemistry.
SUBSTANCE: invention relates to design of a filter for purifying natural and waste water and can be used in public utilities and on industrial plants. The water filter has a steel housing filled with filter material, a distribution and collecting system for feeding and distributing water, wherein vertical alternating rows are placed inside the steel housing parallel to its walls, said rows being in form of closed loops of electropositive electrodes connected in series by a wire and similarly connected electronegative electrodes, with formation of electrochemical current sources which are provided with voltmeters connected in parallel to load resistors, wherein the first row of electronegative electrodes is connected to the housing of the filter.
EFFECT: high efficiency of purifying water and protection of the metal housing from internal corrosion, as well as obtaining electric power.
