METHOD OF WATER (VERSIONS) PURIFICATION AND DISINFECTION AND PLANT FOR WATER (VERSIONS) PURIFICATION AND DISINFECTION Russian patent published in 2009 - IPC C02F9/08

Abstract RU 2360870 C1

FIELD: chemistry.

SUBSTANCE: water purification is realised by assembled in technological succession filter of coarse purification, two pressure sorption filters, which are supplied with control units, filter of fine purification and ultraviolet irradiator. Second pressure sorption filter includes activated carbon as sorbate. Water is supplied to sorption filters in mode of service from above under arterial pressure 0.15-0.60 MPa, and washing of each of the filters is realised in the end of operation cycle by water countercurrent, starting from filter of fine purification. Ratio of body diametre of each sorption filter to rate of water filtration for applied sorbate lies within the range from 60 to 90 s. Plant can be additionally supplied with reverse osmosis unit, which is connected with output of fine purification filter through own pressure pump. Group of inventions allows to ensure purification and disinfection of water with average unit productivity 250-500 dm³/hour during 8-20 hour/day for compactly placed collective users.

EFFECT: ensuring drinkable water quality specified by physico-chemical properties.
