Abstract

PURPOSE: To obtain potable water suitable for preparation of fruit drinks and soft drinks by adding chlorine to raw water and filtering the same then treating the raw water by the use of a revese osmosis membrane of ≥90% Cl removal rate under specific pressures thence pasteurizing the same by ultraviolet rays.
CONSTITUTION: After a prescribed amount of sodium hypochlorite is added to raw water (well water) from a sodium hypochlorite injector, the water is filtered with a 1μ cartridge type filter 2 and is stored in a raw water tank 3. Thence, a valve 4 is opened and a high pressure pump is operated to subject the raw water to reverse osmosis membrane separation under 45W55kg/cm2 operating pressures with a membrane separating module 8 of hollow fiber type mounted with a semipermeable membrane made of cellulose acetate. Thence, the filtrate is treated with an ultraviolet pasteurizating device 10 and is removed in an arrow A direction. The reverse osmosis separating device of hollow fiber type or spiral type consisting of a reverse osmosis membrane of ≥90% Cl removal rate is used.
