What is the concentration ratio of circulating water?

Thread Content

Concentration ratio: The concentration ratio refers to, for a water solution of a certain concentration, if the content of a particular substance in it is S0 and its concentration becomes S1 after evaporation, then the value of S1/S0 is considered the concentration ratio of this solution during the evaporation process. Physical meaning of the concentration ratio: It is a physical quantity that reflects the strength of evaporation capacity of a certain aqueous solution. In the actual field of industrial production, what is often involved are the \"concentration ratio of industrial cooling circulating water\" and the \"concentration ratio of steam boilers\". For industrial cooling circulating water systems, increasing the concentration ratio is of great significance for these systems, as it helps to \"save water resources\". However, for cooling circulation systems, it is not possible to increase this ratio indefinitely. There are constraints; there is constraint two. I. It results in insufficient heat-carrying capacity of water, affecting the quality of “industrial products” ； II. An excessively high concentration ratio increases the salt content in the water, making it easier for the equipment to develop scale. In actual production, the control range adopted by the vast majority of manufacturing enterprises is 1.5–2.5, and this range is far from sufficient; it leads to severe waste of water resources. By using high-quality water treatment chemicals, it is possible to prevent scaling, corrosion, and the growth of microorganisms and algae in the system, and it is also possible to increase the concentration ratio by 5–10 times, thereby saving water resources. Its meaning is self-evident.
