FIELD: chemistry. ^ SUBSTANCE: water filter has a housing, a distribution and a collection system, granular mineral filter material, positive and negative electrodes in form of perforated pipes placed vertically in the filter material. The lower ends of the pipes are joined by a common collector. The positive electrodes are made in form of vertical rods, where the electrodes form alternating rows parallel to end walls of the housing. The pipes are made from aluminium and the rods are made from copper. The distance between neighbouring pipes and rods is between 200 and 240 mm. ^ EFFECT: more efficient purification of natural and waste water from colour, turbidity, iron and petroleum products. ^ 1 dwg |
