METHOD OF PRODUCTION OF THE DRINKING WATER Russian patent published in 2006 - IPC C02F9/12 C02F1/32 C02F1/72 A23L2/00 

FIELD: municipal services; combined methods of production of the drinking water.

SUBSTANCE: the invention is pertaining to the combined methods of production of the drinking water in the water supply systems of settlements with the help of hydrogen peroxide, ultra-violet (UV) irradiation and the ions of the heavy metals. The method provides for at the first stage injection with the help of the dispensers of the water solution, containing salts of copper and zinc at the mass ratio of the ions Cu:Zn equal to 1:5-10; further after the aging within 0.5-1.0 hour the water is treated with peroxide, it is subjected to aging within 0.3-0.4 hours and is gated through the device of the UV-radiation with simultaneous injection through the dispensers of the water solution of the salt of argentum or the a water solution of the salt of argentum and the ammonia water in amount correspondingly equal to 0.0005-0.001 mg/l in terms of Ag⁺ and 1-1.5 mg/l in terms of ammonia. The treatment is mainly conducted at the temperature of 5-50°C, the total ion concentration of Cu and Zn at the first stage of the treatment of 0.6-1.7 mg/l, the hydrogen peroxide - 1-3 mg/l. Optimally the UV treatment is conducted at the irradiated frequency of 0.8-1 Hz and the specific power consumption of 0.8-1 kJ/m³. The invention ensures the ecologically sound effective method of decontamination of the water with its finishing up to the quality of the potable water at utilization of the small amounts of germicides (at their concentration below the officially approved maximum permissible concentration)providing the possibility of its usage in the conditions of the relatively low and heightened temperatures.

EFFECT: the invention ensures the ecologically sound effective method of decontamination of the water with its finishing up to the quality of the potable water at usage of the small amounts of germicides and at the relatively low and heightened temperatures.
