Chemical Treatment for Circulation Cooling Water for water clean

With the rapid development of industry, the issue of industrial Automatic self cleaning filter increasingly causes social concern. As we all know, there are many different treating methods, which can be physical, physical chemistry, chemical, etc., but only the chemical approach is increasingly widely used, because the chemical treatment, by comparison, is simple, and the combined effect of it is more satisfactory. Through increasing the concentration of circulation water, the consumption of chemicals can be greatly reduced, and the cost can also be greatly reduced. According to the chemical treatment method, chemicals shall be added during the process in order to prevent scaling, corrosion and biological silt of the cooling water treatment system. And the commonly used chemicals are corrosion inhibitors, scale inhibitors and biocides, etc.


There are two types of circulation cooling water treatment system: closed-loopcooling Automatic self-cleaning filter and open-loop cooling water system. In the closed-loop water system, water is not exposed in the air, and it is cooled by cooling medium through the heat transfer equipment. By this system, water loss is extremely little for it almost doesn't concentrate, and the classic representative of this system is the internal combustion engine cooling water system. In the open-loop water system,cooling water changes into hot water through heat exchangers by raising the temperature. The hot water aerates and contacts the air through the cooling tower, and the water temperature then is lowered due to evaporation cooling and contact cooling. Finally, the cooling water would be recycled. Open-loop cooling tower system is also known as the cooling tower system, which has been widely used in the factory.
As for the maintenance of circulation cooling water system, cleaning and pre-filming are known as the pretreatment of the chemical treatment. During the process of equipment and pipes installation, debris, sundries, and dust will inevitably be left in the system, and sometimes the corrosion and oil contamination of cooling equipment is also very serious. If these fragments and oil contamination is not cleared up, the next step of prefilming will be greatly affected. Meanwhile, dirt, slime and metal corrosion also exists in the old cooling equipment system, which will seriously affect the efficiency of equipment and heat transfer if not cleaned. Therefore, the cleaning work is essential to drive around the circulation cooling water system. As for the the prefilming, much corrosion inhibitor is cast during the early period of system driving, and its concentration should be reduced after the filmforming to maintain up the film. The purpose of this process is to quickly form a protective film on the metal surface and improve the effect of the corrosion inhibitor.
In a word, we should not only attach much importance to the treatment methods of cooling water, but also pay serious attention to the maintenance of circulation cooling water system.

I studied Water Treatment for many years, manufactured Water Treatment Equipment. Now focused on cooling Water Treatment research.
