Microbiological Control
microbiological control
Microorganisms in the water supply system in the suppression. Such as lakes, reservoirs and other water sources such as plankton blooms of algae caused odor of raw water, and interfere with water filtration, so the addition of copper sulfate or bleach to inhibit microbial growth. Another example is the open type, paper mill white water system circulating fungi, such as the large population of iron bacteria, leading to corrosion of equipment and the ability to reduce the water pipe, so the vote chlorine, such as PCP or quaternary ammonium agents to inhibit microbial growth. Pharmaceutical dosage often intermittent. This is because: ① lakes and reservoirs after dosing, in a period of no loss or disappearance of Pharmacy. ② In the circulating water system with high concentration of pharmaceutical equipment and wall flow on the surface suppress the growth of microorganisms is more effective, while the same concentration of pharmaceutical dosage amount will help to improve concentration. Open recirculating cooling water system of microorganisms is particularly prominent. As the water temperature suitable for all kinds of microorganisms in the nutrient-rich places to thrive. For example, the pond in the sunlight grow algae, fungi attack the surface of the wood, iron in the iron wall surface to breed bacteria, resulting in wood decay, reducing the efficiency of heat transfer equipment, water pipes pitting resistance increases and the emergence of a range of issues. Therefore, microbial control is the open circulation cooling water system one of the main treatment process. |
