Detection and Comparison of Self-made Rapid Membrane Testing Machine for Ultrafiltration membrane and anofiltration membranes

Abstract

Pure water permeability and retention as the important performance index of ultrafiltration membrane and nanofiltration membrane is the key to determine theirs quality. In view of the lack of uniform conditions, uniform standards and mixed enterprise standards, this paper studies the self-made rapid membrane testing machine for the determination of pure water permeability and retention of ultrafiltration and nanofiltration membranes, and compares the data with other testing institutions.
