The makeup water for the cooling tower and water replenishing tower is controlled by the makeup water control system of the integrated water tower purification unit before entering the water tower.

The water replenishment control system consists of a resin softening tank, a sewage pipe, and a controller. The raw water is passed through a sodium cation exchange resin to exchange the hardness components Ca2+and Mg2+in the water with Na+in the resin, thereby adsorbing Ca2+and Mg2+in the water Mg2+， Soften the water and finally replenish the water tower with water; The generated sewage is controlled by a controller and automatically discharged.


The water from the water tower is circulated through a water pump to the metal copper silver ion generator and then enters the sand tank system for filtration.

The metal ion generator consists of a highly modern microprocessor controller and copper silver electrodes. Water flows through a processing box equipped with electrodes, which are stimulated by precise microcurrents to release silver and copper ions. The copper ion release device will maintain the silver ion content in the cooling water below 0.05ppm and the copper ion content below 0.5ppm. Copper and silver positive ions have the effect of killing bacteria and algae, and the water containing copper and silver ions flows into the water tower for continuous circulation.
