HIGH-FLUX PRESSURED MEMBRANE MODULE WATER-PURIFYING APPARATUS

摘要

PURPOSE: A high-flux pressurized membrane module-based water purifying device is provided to reduce a resistance required to filter raw water based on a length of a membrane. CONSTITUTION: A high-flux pressurized membrane module-based water purifying device (110) consists of a hollow housing, an upper header unit (130), a residual water and air supplying module, and a lower header unit (150). A hollow fiber membrane filtering unit is arranged in the housing and filters raw water according to the difference in pressures. The upper header unit includes a first outlet (131) and a second outlet (133). Concentrated water is supplied through the first outlet, and filtered water is supplied through the second outlet. The module supplies residual water from the hollow fiber membrane filtering unit to the outside and is in connection with a hollow fiber membrane unit. The module includes a supplying unit through which air is supplied to remove foreign materials. The lower header unit includes an inlet (151), a third outlet (153), and a fourth outlet (154). Raw water is pressurized and supplied through the inlet. The third outlet is in connection with the supplying hole. Filtered water through the hollow fiber membrane filtering unit is supplied through the fourth outlet.
