Biological pollution is one of the most common and serious problems in the operation of the reverse osmosis membrane (RO) system, especially when the water source is the surface water or the water rich in bacteria. Biological pollution can form the basic conditions of other humus and cause more serious problems, resulting in the decrease of water consumption of membrane system, increase of operating pressure, and decrease the rate of desalination. GT-023-A reverse osmosis membrane system special disinfectant, is dedicated to associated with food production in the process of reverse osmosis membrane sterilization agent, can effectively eliminate and prevent membrane fouling, applicable range widely, as a non oxidizing biocide, the membrane system will not be damaged.
