subject: Comprehensive Analysis On Cooling Water Treatment For Water Treatment [print this page] In the industrial area, cooling water treatment is an indispensable link. Do you know something detailed about it? If your answer is No, I would like to give you a comprehensive analysis on cooling water treatment.
In the first place, a set of complete water treatment system is the key. Generally speaking, the industrial water treatment system design should have the integrated planning for water supply and drainage system, cooling devices and water source. Such a system can be divided into two types, which are open system and closed system. The open water treatment system is fitted for the one that relies on fresh water as water source. If adopting the seawater as condenser's cooling water source, it had better turn to fresh water close-type system or seawater open-type system. In addition, there are many other types when it comes to water treatment system, such as auxiliary cooling water system, closed and opened recirculation cooling water system or once-through cooling system and so on.
In the meantime, when it comes to the concrete cooling water treatment, it also needs the participation of some articles such as cleaning media, anti blocking agent and so on. Take the anti-blocking agent for instance. Its main component is environmental-friendly crystal complex. It can eliminate the rust, Calcium carbonate scale and some stubborn dirt like that on the fluid pipeline device and machines. Besides, it is widely used in the pipeline that is made from stainless steel, steel, iron, plastic, copper or lead. What is more, it will not affect the normal operations and structures of devices. Such a water-solubility material is easy to be dissolved in water and will not produce any toxic gas. At the same time, the antisludging agent also plays the same role with the anti-blocking agent, which is applied to circulating cooling water system and the daily maintenance for water-cooling system of central air-conditioning ad boiler.
Some physical methods are also adopted by cooling water treatment like static-electricity method, membrane treatment, cathode protection method, aluminizing and titanium method. For example, cathode protection relies on the direct current that flows in the device that is protected by electrolytes. Then, the electric potential is moved to the range of protective potential so as to protect the device from corrosion. Another example, the titanium has perfect corrosion resisting property, which is widely applied to chemical process, oil refining and anti-corrosion equipments. The heat exchanger is one of most outstanding applications.
