Abstract

A polymer membrane for water treatment contained a chlorinated vinyl chloride resin with a chlorine content of 58 to 73.2%. According to the present invention  it is possible to provide polymer membranes for water treatment that  along with being able to achieve sufficient filtration capacity and water permeability  have extremely high strength.
