subject: Several Requirements Concerning Cooling Water Treatment For Our Water [print this page] What makes a successful air condition's water treatment system? It's nothing but for preventing deposits, corrosion and microbiological contaminants, to prolong the equipments service life with minimal downtime. And it is said, besides the chemical way of cooling water treatments, to establish an efficient processing management is also very important in cooling water treatment.
Preventing Deposits and Corrosion
For preventing depositions and corrosion, using cutting edge' water treatment inhibitors to keep the equipments away from deposits or corrosion. But please remember! Use the cooling water to carry the protective inhibitors to the cooling-water-contacted equipment. Treating the water likely will not protect your equipment.
Preventing Microbiological Contaminants
The refrigeration system of the air condition always operates in hot summer. Then the plate of the cooling tower can easily cause microbiological deposits. So during these times should periodically select chemical biocides to control microbiological contaminants. Presently, the chemical biocides in the market all have the nature of oxidization; they all have corrosion effect to the iron tube, in long-term applying it would be dangerous to the whole system. Users can choose the chemical which can repress the microbiological growth, then will get several advantages, such as applying little or no chemical biocides to water system which makes pure cooling water system without deposits or corrosion, no more microbiological contaminants, the whole water has no impurities that can save as much as 20% electrical energy when it processing.
Copper and iron are both exist in the closed cooling water system of air condition, attain to get these two kinds of metal protected, should control the PH value between 9-9.9. Because the bluntness scope of PH value of iron is 9-13, that suits for alkali circumstances. However, when the PH value attains to 10, the copper begins to corrode. So hoping the copper and iron were coexisted in cooling water system, strictly controlling PH value at 9-9.9 would be needed, in which way can repress the microbiological growth as well. But when using zinc tube in water system, you have to keep pH value at the neutral scope, because the zinc belongs to neutral metal, whether the pH value too high or too low will effect to the zinc tube.
Generally speaking, reasonably designed, choosing cutting edge' water treatment chemical and properly controlling can successfully complete the job of cooling water treatments; understanding the needs, treatment limitations and objectives of cooling water treatment is also critical to successfully protecting your cooling water equipment. Therefore, it's not so difficult to attain a successful water treatment system.
