METHOD OF PRODUCTION OF THE DESALTED WATER AND THE WATER OF THE HIGH PURITY FOR THE NUCLEAR POWER PLANTS OF THE RESEARCH CENTERS Russian patent published in 2006 - IPC C02F9/08 C02F1/28 C02F1/42 C02F1/44 

FIELD: nuclear power engineering; methods of production of the desalted water and waters of high purity for nuclear power plants of the research centers.

SUBSTANCE: the invention is pertaining to the field of nuclear power engineering, in particular, to the method of production of the desalted water and the water of high purity for nuclear power plants of research centers used at purification of the low-mineralized low-active liquid A-waste. The method provides for the water preliminary purification using the bulk carbon filter and after that using the mechanical microfilter, desalination of the water with the help of the reverse-osmosis filter and afterpurification of the filtrate by the ion-exchange filter. Then the purified water is collected in the tank. The reverse-osmosis purification conduct by two series filters. At that the filtrate of the first filter is routed through the intermediate tank to the inlet of the second filter, the filtrate of the second filter is routed to the ion-exchange filter for afterpurification. The concentrate of the second reverse-osmosis filter is routed into the tank of the initial waters, the concentrate of the first osmosis filter is routed to the water discharge or neutralization. The invention allows to increase the degree of desalting of the initial waters and ensures realization of purification without usage of the chemical reactants.

EFFECT: the invention allows to increase the degree of desalting of the initial waters and ensures realization of purification without usage of the chemical reactants.
