Circulating water treatment cannot do without SDIC

Human daily life cannot do without water, and industrial production also cannot do without water. With the development of industrial production, water consumption is increasing, and many regions have already experienced water shortage. Therefore, reasonable and economical water use has become an important issue in the development of industrial production.

Industrial water mainly includes boiler water, process water, cleaning water, cooling water, sewage, etc. The largest water consumption among them is cooling water, accounting for over 90% of industrial water consumption. Different industrial systems and uses have different requirements for water quality; However, the cooling water used by various industrial sectors has basically the same requirements for water quality, which has led to the rapid development of cooling water quality control as an application technology in recent years. In factories, cooling water is mainly used to condense steam, cool products or equipment. If the cooling effect is poor, it will affect production efficiency, reduce product yield and quality, and even cause production accidents.

Water is an ideal cooling medium. Because the presence of water is very common, compared to other liquids, water has a larger heat capacity or specific heat, and its latent heat of vaporization and melting is also very high.

Like water, air is also a commonly used cooling medium. But compared to air, the thermal conductivity of water is about 24 times higher. Therefore, when the cooling effect is the same, water cooling is much smaller than air cooling equipment. Large industrial enterprises and factories with high water consumption generally use water cooling. The commonly used water cooling systems can be divided into three categories: direct current systems, closed systems, and open evaporation systems. The latter two types of cooling water are both recycled, so they are also called circulating cooling water systems.

It is recommended to use green water treatment agent sodium dichloroisocyanurate for circulating water treatment, which can effectively kill various pathogenic microorganisms such as bacterial spores, bacterial propagules, fungi, etc. It has a special killing effect on hepatitis virus, quickly killing and strongly inhibiting blue-green algae, red algae, seaweed and other algae in circulating water, cooling towers, water tanks and other systems. It has a thorough killing effect on sulfate reducing bacteria, iron bacteria, fungi, etc. in the circulating water system.
