Due to the different working pressure of the boiler, the water quality requirements and control methods are different. The higher the working pressure of the boiler, the higher the requirements for water quality and the stricter the control. The purpose of water quality control is to prevent scaling and corrosion in the boiler and its…

Since the hardness of water is mainly formed and expressed by calcium and magnesium, cation exchange resin (water softener) is generally used to replace Ca2+and Mg2+(the main component of scale formation) in water. With the increase of Ca2+and Mg2+in the resin, the efficiency of removing Ca2+and Mg2+by the resin decreases gradually.The softening device is divided…
