Background
In the running process of the circulating water, as the water is evaporated and lost, the concentration of calcium, magnesium, chlorine, sulfate radical and other ions in the circulating water is increased, the soluble solids and suspended matters are increased, and the microorganisms are greatly propagated. As a result, scale formation and corrosion occur in the pipes of the circulating water system, resulting in reduced heat exchange efficiency and corrosion under the scale, which wastes water and electricity and shortens the service life of the system. Therefore, in order to limit the unrestricted increase in salt content, a portion of the concentrate must be removed while fresh water is fed in.

If the concentration multiple of the circulating water is too high, the scaling tendency of the water is increased, the difficulty of corrosion control is increased, and therefore, the concentration multiple of the circulating water is reasonably controlled.
