摘要
A hydrophilic filtration membrane having high chemical resistance, high strength, high water permeability and high blocking performance, and being superior in fouling resistance is provided. A hydrophilic filtration membrane containing a hydrophilic polyethersulfone having a contact angle of 65 to 74 degree, a molecular weight of 10,000 to 100,000, and the number of hydroxy groups of 0.6 to 1.4 per 100 polymerization repeating units. The hydrophilic filtration membrane may additionally contain a polyvinylpyrrolidone having a molecular weight of 10,000 to 1,300,000.
