Which impurities can be removed by deionized water equipment? Author: many companies only know to buy pure water equipment, pure water equipment but then the function and role of little knowledge, today to introduce to you about the environmental effect of deionized water equipment.   Deionized water equipment mainly removes impurities in water and purifies water. Then, which impurities can be removed by deionized water equipment? Deionized water equipment can dissolve inorganic salts in water, such as potassium, calcium, sodium, magnesium and other substances in the water, which are all in the water in an ionic state. In the semiconductor industry, water cleaning equipment is often needed. If the water contains inorganic salts and other substances , Will cause the circuit surface to be short-circuited or even burned.   Cation exchange grease and anion exchange resin are used separately, which is easy to regenerate. The mixed bed ion exchange resin is used in the final stage of ion exchange and plays a role as a gatekeeper. This water can reach 18 megohm-cm (25 degrees Celsius). Dissolved organic matter: There are industrial wastes, detergents, biodegradable products and metabolic products of microorganisms. These can be removed by the activated carbon adsorption method. The carbon bed should be placed before the ion exchange resin, because the activated carbon itself will bring impurities. It must be noted that the water entering the resin bed must first remove organic matter, because the ion exchange resin is easily contaminated by organic matter (such as humic acid). Reverse osmosis can remove organics with a molecular weight greater than 300, and organics with a molecular weight less than 300 can remove 90%.   The above is an introduction to the substances that can be purified by deionized water equipment. If you don't understand, please come to consult the editor of environmental protection.
