What should I do if the reverse osmosis membrane of industrial EDI ultrapure water equipment is contaminated? Author of the article: current industrial EDI ultra-pure water equipment technology developed rapidly, with a simple process, saving energy and cost advantages, can effectively remove the water, sand, rust, pigments, debris, to remove organic matter and other harmful ingredients. Industrial EDI ultrapure water equipment mainly relies on the reverse osmosis system. Once the reverse osmosis system is polluted, it will directly affect the quality of the desalinated water. Pollution hazards of reverse osmosis system: Pollution of reverse osmosis system usually refers to the adhesion and deposition of medium sand, rust, pigment, debris, organic matter and microorganisms on the membrane surface or the precipitation of inorganic ions in the water. Pollution. The reverse osmosis membrane pollution of industrial EDI ultrapure water equipment is a gradual development process. In the early stage of reverse osmosis membrane pollution, the impact of industrial EDI ultrapure water system is not particularly obvious, and the harm to production is not great. If it is carried out in time Cleaning can basically be restored. However, if it is not handled in time, the system will continue to deteriorate, and severe pollution will have a serious impact: the response is the decline in the quality of the reverse osmosis effluent. The water produced by reverse osmosis has decreased and water consumption has increased. Increased water and electricity consumption. The life of the reverse osmosis membrane element is shortened. How to clean reverse osmosis membrane elements: Under normal circumstances, when the standardized flux drops by 10-15%, or the system desalination rate drops by 10-15%, or the operating pressure and the pressure difference between sections increase by 10-15%, RO should be cleaned. system. The cleaning frequency is directly related to the pretreatment degree of the system. When SDI15<3, the cleaning frequency may be 4 times a year. When SDI15 is around 5, the cleaning frequency may be doubled, but the cleaning frequency depends on the actual situation of each project site. The above content is the introduction about the pollution of the reverse osmosis system of the industrial EDI ultrapure water equipment. If you find that the industrial EDI ultrapure water equipment is polluted, please clean and maintain the reverse osmosis system in time to avoid affecting the industrial EDI ultrapure water equipment Normal operation.
