Abstract
PURPOSE: To obtain the high-purity permeated water by circulating the permeated water after a reverse osmotic membrane treatment to mix it with a water to be treated, and passing this mixed water through the reverse osmotic membrane apparatus.
CONSTITUTION: Water F to be treated is stored in a cell V temporarily, passed through a pump Po, and is treated in the reverse osmotic membrane apparatus A to divide the water into the permeated water and the non-permeated water. 10 to 80% preferably 20 to 60%, of this permeated water is let to be circulating permeated water which is returned to the cell V to mix with water F to be treated. The mixture is let to be supply water F1. Again, this supply water is passed through the reverse osmotic membrane apparatus A. By mixing the permeated water P after the treatment with water F to be treated, the salt concentration of the supply water F, can be lowered. Accordingly, the high-purity permeated water can be obtained, the contamination of the reverse osmotic surface M can be protected, and the treatment efficiency can be enhanced.
