The circulating water system is a common cooling water system in industrial production, which achieves the purpose of saving water by continuously recycling water resources. However, with the continuous development of industrial production, the circulating water system is facing more and more challenges and problems, such as scale, microbial growth, corrosion, etc. These problems not only affect the normal operation of the system, but also have a negative impact on the production efficiency and product quality of the enterprise. Therefore, the treatment of circulating water system has become an indispensable part of industrial production.
1. The importance of circulating water system treatment.
Circulating water system treatment is an important part of industrial production, which can ensure the normal operation of the system and improve the production efficiency and product quality of enterprises. First of all, the circulating water system treatment can effectively remove impurities and harmful substances in the water, and prevent the occurrence of scale, microbial breeding, corrosion and other problems. Secondly, the circulating water system treatment can improve the cooling effect of the cooling water, thereby reducing the energy consumption and production cost of the enterprise. In addition, the treatment of the circulating water system can also extend the service life of the equipment and reduce the maintenance and replacement costs of the enterprise.
2. Common problems in the treatment of circulating water system.
Common problems in the treatment of circulating water systems include scale, microbial growth, corrosion, etc. These problems not only affect the normal operation of the system, but also have a negative impact on the production efficiency and product quality of the enterprise.
1.Scale: Scale is one of the common impurities in circulating water, which is formed by the crystallization of minerals and ions dissolved in water at high temperatures. Scale will adhere to the surface of the equipment, affecting the heat transfer effect and normal operation of the equipment.
2.Microbial growth: Circulating water contains a large number of microorganisms, such as bacteria, algae, etc. These microorganisms can multiply in the water, affecting the quality of the water and the proper functioning of the equipment.
3.Corrosion: Dissolved oxygen and pH in circulating water can cause corrosion to equipment, which can affect the life and safety of equipment.
Third, the method of circulating water system treatment.
In order to solve the common problems in the treatment of circulating water systems, a series of treatment methods need to be adopted.
1.Physical treatment methods: Physical treatment methods include precipitation, filtration, adsorption, etc. These methods improve the quality of water by removing suspended solids, impurities and harmful substances from the water.
2.Chemical treatment methods: chemical treatment methods include dosing, ion exchange, electrochemistry and other methods. These methods can remove dissolved salts, pH, dissolved oxygen and other harmful substances in water through chemical reactions, thereby preventing scale, microbial growth, corrosion and other problems.
3.Biological treatment methods: Biological treatment methods include activated sludge method, biological filter method, etc. These methods use the metabolism of microorganisms to break down organic matter and harmful substances in water, thereby improving the quality of water.
Fourth, the future development trend of circulating water system treatment.
With the continuous development of industrial production and the improvement of environmental protection requirements, the treatment of circulating water system will develop in the direction of more efficient, environmental protection and energy saving. In the future, new technologies and new materials will be used more in the treatment of circulating water system, such as membrane separation technology, ultrafiltration technology, reverse osmosis technology, etc., to improve the treatment effect and rate of water. At the same time, the treatment of circulating water system will pay more attention to environmental protection and energy saving, such as the use of low-phosphorus detergents, the use of solar energy and other renewable energy.
In short, recirculating water treatment is an indispensable part of industrial production. Only through scientific and reasonable processing methods and technical means can we ensure the normal operation of the system and improve the production efficiency and product quality of the enterprise. With the continuous development of industrial production and the improvement of environmental protection requirements, circulating water system treatment will become one of the important directions of industrial development in the future.
