Will industrial stainless steel water softening equipment be affected by pollutants? Author: stainless steel industrial water softening equipment in the course will be some pollutants, these substances have a great impact on industrial water softening equipment, stainless steel, stainless steel affects the work of industrial water softening equipment, the impact of ultra-pure water equipment than Large pollutants include hardness (calcium, magnesium), organic matter, suspended solids, variable metal ions (iron, manganese), oxidizers (chlorine, ozone), carbon dioxide (CO2), and bacteria. Then the pollutants affect industrial stainless steel softening equipment What effect will it have? Chlorine and ozone will oxidize ion exchange resins and ion exchange membranes, causing the function of ultrapure water equipment components to decrease. Oxidation can also significantly increase the TOC content, contaminate ion exchange resins and membranes, and reduce ion migration speed. In addition, oxidation causes the resin to crack, and the pressure loss through the component will increase. Iron and other variable metal ions can catalyze the oxidation of the resin and permanently reduce the performance of the resin and membrane. Hardness can cause fouling in reverse osmosis and industrial stainless steel softened water equipment units. Fouling generally occurs on the surface of the concentrated water chamber membrane, where the pH value is high. At this time, the pressure difference between the inlet and outlet of the concentrated water increases, and the amount of current decreases. Minimizing the hardness of the inlet water will extend the cleaning cycle and increase the water utilization rate of the industrial stainless steel softening equipment system. Suspended substances and colloids can cause pollution and blockage of membranes and resins. The blockage of resin gaps leads to increased pressure loss of industrial stainless steel water softening equipment components. The organic matter is attracted to the surface of the resin and the membrane to cause pollution, so that the efficiency of the contaminated membrane and the resin to transfer ions is reduced, and the resistance of the membrane stack will increase. Carbon dioxide has two effects. First, CO32- and Ca2+ and Mg2+ form carbonate scale. The formation of this scale is related to the ion concentration and pH of the water supply. Secondly, because the charge of CO2 is related to the pH value, and its removal by RO and industrial stainless steel softening equipment depends on its charge, its removal efficiency varies. Even lower CO can significantly reduce the resistivity of product water. Bacteria cause algae growth and slime formation, increase the pressure loss of the membrane block and reduce water quality.
