METHOD OF DESALINATION OF NATURAL WATER AT STAGE-BY-STAGE SETTLING OF ADMIXTURES FOR THEIR UTILIZATION AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2001 - IPC

FIELD: methods of desalination of sea water. SUBSTANCE: plant is provided with reservoir for accumulation of concentrate. Starting water is treated by first, at least one target reagent. Immediately after deposition, treated water is fed to tangential filter; permeate is continuously discharged and concentrate is returned to reservoir, after which concentrate is repeatedly passed through filter till it looks required; concentrate is directed for utilization and permeate is treated once more by target reagent; at the beginning of deposition, it is passed through additional filter mounted in succession which is identical to first one; permeate is continuously discharged and concentrate is fed to another reservoir for accumulation, after which this concentrate is repeatedly passed through additional filter and till it looks as required , concentrate is directed for utilization. EFFECT: simplified construction of plant; reduced overall dimensions; increased cost of separated admixtures; reduced cost of desalination of water. 3 cl, 1 dwg, 2 tbl
