Background

Reverse Osmosis (RO) is a fine membrane separation product that can effectively retain all dissolved salts and organic substances with molecular weight greater than 100, while allowing water molecules to pass through. Reverse osmosis membrane is widely used in sea water and brackish water desalination, boiler make-up water, industrial pure water and electronic grade high-purity water preparation, drinking pure water production, wastewater treatment, special separation and other processes, but reverse osmosis device runs for a long time, and pollutants (such as inorganic salt scale, organic matters, microorganisms, metal oxides, colloids and the like) can be deposited on the membrane surface, so that system performance is reduced, usually, RO system operation and maintenance personnel carry out chemical cleaning on the membrane, and if the performance can not be recovered after cleaning, the membrane element needs to be detected, and the reason of membrane element performance reduction is found out. Because it is difficult to determine which specific membrane element has a reduced performance, the field operator generally sends all membrane elements in the membrane shell with abnormal conductivity back to the original manufacturer for detection, or even completely replaces the membrane elements, however, the number of membrane elements in each membrane shell is usually 4-6 or more, if the membrane elements are completely detected or replaced, the labor and financial resources are greatly consumed, and the running cost of the RO is increased.
