PURPOSE:To prevent the clogging of a passage in the treatment of high-turbidity waste water by providing many tubular membranes each having 2.5-4.0mm inner diameter in parallel in a vessel. CONSTITUTION:The waste water to be treated is introduced into the tubular membrane 2 from an opening 2a at the one end of the membrane 2 and permeated, the permeated water passes the space between the membrane 2 and the inner surface of a cylindrical pressure vessel 1 and is discharged from a water outlet 5, and the concd. water is discharged from an opening 2b at the other end of the membrane. Since the inner diameter (d) of the membrane is controlled to 2.5-4.0mm, the consumption of energy for water supply can be reduced, and the clogging of the passage can be prevented even in the treatment of high-turbidity waste water. |
