METHOD FOR REMOVING SOLUBLE MANGANESE

摘要

PROBLEM TO BE SOLVED: To provide a method for removing soluble manganese by using a compact apparatus, capable of easily adjusting the operation of the apparatus even when the volume of raw water fluctuates. SOLUTION: This method comprises: the first process of adding sodium-hypochlorite 14 and manganese sand 18 which is a catalyst particle to raw water 12 containing the soluble manganese in a mixing tank 10 and mixing the same; the second process of feeding treated water 22 treated in the first process to a membrane module 26 in which the treated water is separated into treated water 28 and a membrane separation substance 30 by membrane filtration; and the third process of recovering the manganese sand 18 from the membrane separation substance 30 to return the recovered manganese sand 18 to the first process for reuse.
