专利汇可以提供Method for making ultrapure water专利检索,专利查询,专利分析的服务。并且PURPOSE: To suppress the lowering of flux, by biologically treating recovered water in an ultrapure water treatment system and subsequently injecting hydrazine to water before performing membrane separation.
CONSTITUTION: Water passing through the ultraviolet oxidizing apparatus 4 of a recovery system A is introduced into a bioreactor 13 to be biologically treated under an aerobic condition. By this method, organocarbon becomes CO
2 or is taken in a bacterial cell. Further, a hydrazine tank 15 for supplying hydrazine and a chemicals injection pump 6 are provided to a piping system for supplying treated water from the bioreactor 13 to the RO membrane separation apparatus 7 of an ultrapure water making system B to continuously or intermittently inject hydrazine. By this method, it can be prevented that bacteria are adhered to the RO membrane of the separation apparatus 7 to form a gel layer.
