MEMBRANE TREATMENT METHOD AND MEMBRANE TREATMENT EQUIPMENT USING MEMBRANE MODULE

摘要

PROBLEM TO BE SOLVED: To provide a membrane treatment method and membrane treatment equipment using membrane module capable of fouling countermeasure without bringing about a cost increase with simple equipment. SOLUTION: The membrane treatment method and membrane treatment equipment comprises a membrane treatment tank 2 and a membrane module 1 installed on the center of the tank 2, wherein the membrane module which continues filtration while causing raw water to flow in is used, and the raw water is introduced along the direction of the outer circumferential tangent toward the inner part from the outer part of the membrane treatment tank 2 to form a swirling flow in the tank 2.
