Scope

This document describes the identification methods of contaminants adhering to the surface of reverse osmosis membranes using thermogravimetry, scanning electron microscopy-energy spectroscopy, infrared spectroscopy, and X-ray diffraction.
This document is applicable to the identification of inorganic contaminants, organic contaminants, and microbial contaminants adhering to the surface of reverse osmosis membranes, as well as their mixed contaminants. The identification of contaminants on other separation membranes can be referenced for implementation.
