The concentration of dissolved solids is controlled by removing a portion of the highly concentrated water and replacing it with fresh make-up water. The dissolved solids can also lead to corrosion problems. If the concentration gets too high, the solids can cause scale to form within the system. As more water evaporates, the concentration of dissolved solids increases. Drift loss is small compared to evaporation and blowdown and is controlled with baffles and drift eliminators.īlowdown: When water evaporates from the tower, dissolved solids (such as calcium, magnesium, chloride, and silica) remain in the recirculating water. Water leaves a cooling tower system in one of four ways.Įvaporation: The primary function of the tower and the method that transfers heat from the cooling tower system to the environment.ĭrift: A small quantity of water may be carried from the tower as mist or small droplets. The thermal efficiency and longevity of the cooling tower and equipment depend on the proper management of recirculated water.
