Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To provide a method of treating sewage in which the required quantity of air for washing the membrane surface of a membrane cartridge is reduced and the permeated flow rate is increased. SOLUTION: According to the concentration of suspended matter contained in water to be treated 2, clearance between membrane cartridges 5, 5 which is a flow path for a gas-liquid two-phase flow containing air jetted from a diffusion pipe 8 is properly set. Since when the clearances between the membrane cartridge 5, 5 are narrowed, the area of the flow path per membrane area is made small, for the definite air supply quantity, the narrower the clearances are, the larger the flow rate of the gas-liquid two-phase flow is, and large membrane surface shear force is applied. Even when the supplied quantity of air is lessened, the flow rate of the gas-liquid two-phase flow per flow path ares is maintained.
