Abstract: PURPOSE: A membrane for water treatment is provided to be able to implement a membrane for water treatment with a high water permeability and membrane pollution prevention, and a manufacturing method thereof, and to be able to reduce the operation cost and to maintain the lifespan of the membrane for a long time. CONSTITUTION: A membrane (10) for water treatment includes nanofibers (20) and has a surface charge (30). The nanofibers form a net form, and have the diameter of 10-1000 nm. The nanofibers include ionic polymer and non-ionic polymer. The ionic polymer has an ionic functional group. The ionic functional group includes at least one selected from the group consisting of sulfonate, carboxylate, phosphate, amine and ammonium. The polymer having at least one functional group selected from the group consisting of sulfonate, carboxylate and phosphate includes at least one selected from the group consisting of Nafion, sulfonated polyether-ether-ketone, and carboxylated polyether-ether-ketone. A manufacturing method of a membrane for water treatment comprises a step of manufacturing a mixed solution by mixing ionic polymer and non-ionic polymer; a step of manufacturing a membrane including nanofibers with the mixed solution by using the elctrospinning method; and a step of heat-treating the membrane.
