FIELD: chemistry.

SUBSTANCE: system includes two functional units: pre-purifying and decontamination, as well as final finishing. The first unit comprises a sequestered settler 2, a fecal pump 3, a mixer 4, a perhydrol dosing pump 6, and a filter 8 for separating large fractions from water. The final finishing unit includes a series-connected intermediate tank 10, a circulation pump 12, an ejector-cavitator 13, a sand contact filter 15, an ozone-generating UV lamp 16. The system also contains a sack filter 17.

EFFECT: increasing the efficiency of water purification, simplifying the design, increasing the reliability of the entire system with the simultaneous elimination of the ozonator unit and reducing the energy consumption.
