WATER TREATMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a water treatment apparatus which simplifies a circuit configuration and circuit switching control for reversal washing of a membrane separator immersed in raw water of a raw water tank. SOLUTION: The membrane separator 13 for removing pollutants and bacteria in the raw water A by using hollow fiber membranes having water permeable pores is immersed and installed in the raw water tank 11 for receiving the feed of the raw water A. A treated water suction pipe 17 is connected to the passage of membrane permeate that has permeated through each hollow fiber membrane of the membrane separator 13, and the suction port 19 used at normal rotation of a normally and reversibly rotatable vortex pump 18 is connected to the treated water suction pipe 17. A treated water supply pipe 21 connected to a discharge port 20 used at normal rotation of the vortex pump 18 is inserted into a treated water tank 22 for storing treated water.
