摘要： PROBLEM TO BE SOLVED: To obtain treated water of high water quality at high level by removing calcium and magnesium in wastewater forming scale components in post processes by using a relatively simple device without requiring any coagulation treatment with polymers.SOLUTION: Carbonate group is added to water containing calcium and magnesium to deposit calcium carbonate and magnesium hydroxide under the alkaline condition of ≥pH 11, and reaction liquid containing deposits is subjected to solid-liquid separation by an MF membrane separator. Condensed water of the MF membrane separator is circulated to the raw water side. Treated water of high water quality of SS concentration of ≤10 mg/L can be consistently obtained by performing the solid-liquid separation by the MF membrane without performing any coagulation treatment with polymers. By modifying deposited sludge by circulating the condensed water from the MF membrane separator, sludge of high concentration can be obtained, the treatment efficiency of discharged sludge can be improved, and the sludge treatment cost can be reduced.
