WATER TREATMENT EQUIPMENT

摘要

PURPOSE:To shorten settling time by providing a filtration membrane in a membrane separation equipment to the flow path of mixed liquid circulated in an anaerobic fermentation tank. CONSTITUTION:A plurality of filtration membranes 5A are formed into a tubular shape and parallel provided to the direction orthogonal for the circulation flow path R of mixed liquid. In order to take out only treated water from the mixed by using suction force due to a suction pump 3 as motive force of filtration, both respective filtration membranes 5A of a membrane separation equipment 5 and the suction pump 3 are communicated and connected with a connection pipe 8 for recovering treated water. Thereby, the initial cost can be reduced.
