FIELD: chemistry.
SUBSTANCE: invention relates to the field of natural water purification for economic-drinking and industrial water supply, including slightly muddy coloured low-temperature water. The method includes the reagent processing of water with a coagulant and a flocculant, carrying out volume coagulation under the conditions of mechanical mixing, clarification in horizontal settling tanks, equipped with floatation chambers at the output, filtration, decontamination of the purified water, collection of washing water into a balancing reservoir with its further mixing with initial water.
EFFECT: provision of the drinking water quality independent on seasonal fluctuations of the initial water quality and temperature conditions, increased degree of clarification of water to be coagulated before filtration, reduction of the washing water consumption.
