Chemical method and physical method of circulating water treatment agent

The circulating water treatment agent includes chemical method and physical method. The cooling circulating water system mostly adopts chemical method, which includes water treatment system, dosing system, cleaning system and backwashing system. The hardness of the system make-up water is removed by ion exchange and salts are combined with circulating water to add scale inhibitor, corrosion inhibitor and bactericide, and the system is regularly cleaned and backwashed to form a complete set of water treatment technology. This method has good effect, can prolong the service life of equipment, has high operating efficiency, saves energy, and is applied by major companies at home and abroad. Large air-conditioning cooling water treatment systems are gradually adopted, with a broad prospect.
