Hardness removal equipment The total amount of calcium and magnesium ions in water is called the total hardness of water. It is easy to produce insoluble sediment (scale) in daily life and industrial water use, which will bring a lot of inconvenience to life and production. The cooling water with high hardness will make the heat exchanger form scale, seriously hinder the flow channel, greatly reduce the heat exchange effect, produce perforated corrosion and damage equipment; As boiler water, it will scale on the heating surface of boiler, but the thermal conductivity will become worse; Textile printing and dyeing will cause fabric spots, affect the beauty and quality of products and so on. Working principle of softer: the exchange function of radical in ion exchange resin is used to remove the hardness compositions (such as Ca2+, Mg2+) in water and soften the hard water, so that the harm to pipeline and equipment caused by water scale can be reduced and the service life of equipment can be prolonged. Hardness of water quality treated with JPYSF single or multistage softener is 鈮?.02mmol/L. Softener failure requires regeneration with sodium chloride. Introduction to softener, boiler water softening and automatic softener Working principle of softened water equipment: because the hardness of water is expressed by calcium and magnesium, the cation exchange resin (softener) is used generally to replace Ca2+ and Mg2+ the main component of scale formation) in water. With the increase of Ca2+ and Mg2+ in resin, the effectiveness that resin removes Ca2+ and Mg2+ is gradually reduced. When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to wash the resin layer with brine in the salt box, replace the hardness ions on the resin, and discharge the waste liquid from the tank with the regenerated waste liquid. Resin returns to softening exchange function. Since the hardness of water is mainly formed and expressed by calcium and magnesium, the principle of sodium ion exchange softening treatment is to exchange the hardness composition of water Ca2+, Mg2+ with the Na+ in the resin through the sodium cation exchange resin, thus adsorbing the Ca2+ and Mg2+ of water to soften the water. If sodium resin is represented by RNa, the exchange process is as follows: 2RNa+Ca2+=R2Ca+2Na+2RNa+Mg2+=R2Mg+2Na+. When water passes through the sodium ion exchanger, the Ca+ and Mg+ in the water are replaced into Na+. The general operation flow of control valve is: operation, backwash, salt absorption, slow wash, salt tank water, conventional well-flushing Qingzhou Yuancheng Water Treatment Equipment wins the market with integrity, and concentrates on joint development with customers!China Activated Carbon Filter website:http://www.ycwatermaker.com/multi-meida-water-filter/activated-carbon-filter/
