The selection of circulating water treatment agent schemes should be determined according to the specific circulating water system characteristics, water quality conditions, and processing goals. The following is a general circulating water treatment agent solution:
Antibacterial agent: The circulating water system is vulnerable to contaminated by microorganisms such as bacteria, algae, and fungi. The antibacterial agent can effectively inhibit the growth of microorganisms and prevent biological pollution. Common antibacterial agents include chlorine oxyl acid (BCDMH), polychromic benzene (PCB), etc.
Correspondent: Metal corrosion problems that may exist in circulating water. The corrosion agent can form a protective membrane layer to reduce the corrosion rate of metal. Common corrosion agents include organic phosphorus, nitrate and silicate.
Differentians: The suspension or sediments that may exist in circulating water will affect the thermal exchange efficiency of the system and the normal operation of the equipment. The dispersant can effectively prevent the gathering and attachment of the suspension and the sediment, so that it keeps it suspended in the water. Common dispersing agents include polyacrylamide (PAM) and polyphospholic acid.
PH regulator: The pH value of circulating water has an important impact on the stability of the system and the life of the equipment. The pH regulator can help maintain the proper pH range of circulatory water and prevent problems such as acid and alkali corrosion and precipitation. Common pH regulators include sodium hydroxide, sulfate, sodium bicarbonate, etc.
Chelators: Metal ions that may exist in circulating water will cause problems such as precipitation and dirt pads. The chelating agent can form a stable complex with metal ions to prevent its precipitation and promote its removal. Common chelated agents include EDTA (ethyleine tetharine) and DTPA (diopyropenyl triamine).
It should be noted that the selection and use of circulating water treatment agent schemes should be adjusted according to the specific conditions of the circulating water system and the results of water quality analysis to ensure that the amount and ratio of the pharmaceutical agent should be reasonable, and the operation is performed in accordance with the instructions of the use. At the same time, regularly monitor the water quality indicators of circulating water, adjust and optimize the pharmaceutical solution in a timely manner to ensure the stable operation of the circulating water system and the normal work of the equipment. It is best to consult a professional water treatment technicians or suppliers when choosing and using circulating water treatment agents.
