What chemicals are commonly used in water treatment plants during winter

Water treatment plants typically use the following types of chemicals during winter: coagulant Polyaluminum chloride (PAC): an inorganic polymer coagulant with strong adaptability and good treatment effect on low-temperature and low turbidity water. It can quickly destabilize, flocculate, and precipitate suspended particles and colloidal ions in water. Polyferric sulfate (PFS): It has a fast hydrolysis rate, a large adsorption capacity of flocs formed, a dense structure, and a fast settling rate, making it particularly suitable for low-temperature and low turbidity water treatment. Polysilicate metal salts: can enhance the coagulation effect under low temperature conditions, promote the formation and precipitation of flocs. flocculant Polyacrylamide (PAM): When used in combination with coagulants, it can improve the strength and settling performance of flocs, especially at low temperatures, and effectively promote the coagulation process. Activated silica: can improve the structure of flocs, enhance coagulation effect, and help remove small particles and colloidal substances from water. disinfectant Liquid chlorine: Low cost, simple operation, long-lasting disinfection effect, but attention should be paid to safe storage and use, as it may produce disinfection by-products. Chlorine dioxide: high disinfection efficiency, no by-products, good bactericidal effect on bacteria, viruses, algae, etc., suitable for low-temperature water disinfection. Sodium hypochlorite: prepared on site by electrolyzing saline solution, safe and leak free, but the effective chlorine is easily decomposed by temperature, and the dosage needs to be controlled. Ozone: a strong oxidizing agent with good disinfection effect but poor stability. It needs to be prepared and used on site, and is commonly used in pre oxidation or deep treatment stages. Oxidizing agent Potassium permanganate composite salt: It can oxidize organic matter, iron, manganese and other substances in water, and also has a certain bactericidal and disinfectant effect, but the dosage should be strictly controlled to avoid discoloration of the water body. Hydrogen peroxide: a strong oxidant that can be used to remove organic matter and odors from water, or combined with ozone to reduce the generation of bromate. It is suitable for poor water quality in winter. pH adjuster Sodium hydroxide: Used to adjust water pH levels, ensuring processes such as coagulation and disinfection occur within an appropriate acidic or alkaline environment. Particular attention to adjustment is required during winter when water temperatures are low and pH levels are prone to fluctuation. Sodium carbonate: Also used to adjust pH levels, it simultaneously provides alkalinity, aiding in maintaining the chemical stability of the water body. Algaecide Copper sulfate: When algae may still be active in winter, adding an appropriate amount of copper sulfate can inhibit algae growth and prevent algae from causing blockages or affecting water quality during water treatment. The use of the above chemicals needs to be flexibly adjusted according to local water quality characteristics, water treatment processes, and actual operating conditions to ensure that water quality meets safety standards.
