METHOD OF FINAL PROCESSING OF DRINKING WATER Russian patent published in 2014 - IPC C02F1/28 C02F1/50 C01B31/08 

FIELD: chemistry.

SUBSTANCE: invention relates to processing of drinking water with application of sorption purification. Method of final purification of drinking water includes mechanical filtration of water through wooden activated carbon sorption charge and introduction of sodium hypochlorite into initial filtered water. Filtration of initial water is carried out at specified rate, corresponding to time of contact of filtered water with sorption charge for 8-12 minutes. Index of oxidisability in filtrate is periodically measured. If index of oxidisability in filtrate increases by 25-30%, specified rate of filtration is reduced by 2-3 fold. Sodium hypochlorite is introduced into initial filtered water with concentration 60-80 mg/l, after which sorption charge is washed with reverse flow of purified water.

EFFECT: invention makes it possible to increase sorption capacity of carbon in the process of final processing of water.
