Water Treatment Chemicals: A Comprehensive Guide
Water treatment chemicals are substances used to purify raw water, make it fit for human consumption or industrial uses, and reduce the impact of effluents on the environment. While natural water sources are contaminated with impurities, including microorganisms, minerals, and organic matter, such chemicals play a vital role in disinfecting and transforming water into safe and clean water.
SJZ CHEM-PHARM CO., LTD. is one of the leading manufacturers and exporters of water treatment chemicals, including food additives, industrial chemicals, and pharmaceutical intermediates. The company has been certified with ISO9001 quality system, thus meeting the stringent global standards of quality management systems.
Boiler and Cooling System Treatments
Boiler and cooling systems are widely used in industrial plants to regulate the temperature and prevent damage from overheating or freezing. However, such systems require water treatment chemicals to prevent corrosion, scaling, fouling, and microbiological growth. Some of the common chemicals used in boiler and cooling system treatments include oxygen scavengers, scale inhibitors, dispersants, biocides, and alkalinity builders.
Oxygen scavengers are used to remove dissolved oxygen from water, thus reducing the formation of corrosion products. Scale inhibitors prevent the precipitation of minerals, such as calcium and magnesium, which can cause scale buildup and reduce heat transfer efficiency. Dispersants are used to maintain the solubility of minerals and reduce the risk of fouling. Biocides prevent the growth of bacteria, algae, and fungi, which can cause biofilm formation and system deterioration. Alkalinity builders are used to maintain the pH of water and prevent acid corrosion.
RO Plants Treatments
Reverse osmosis (RO) is a technology used to remove dissolved salts, organic matter, and other impurities from water by passing it through a semi-permeable membrane. RO plants require water treatment chemicals to enhance membrane performance, prevent fouling, and disinfect the influent and effluent water. Some of the common chemicals used in RO plants treatments include antiscalants, biocides, dispersants, and pH adjusters.
Antiscalants are used to prevent the formation of scales on the membrane surface, which can reduce water flux and recovery. Biocides and dispersants are used to prevent and remove biofilm formation on the membrane surface, which can reduce the rejection rate and increase the differential pressure. pH adjusters are used to maintain the pH of water and prevent precipitation of salts on the membrane surface.
Closed Loop and Building Services Treatments
Closed-loop systems and building services, such as heating, ventilation, air conditioning, and water supply networks, require water treatment chemicals to prevent corrosion, scaling, and microbiological growth. Such systems use recirculating water that comes in contact with pipes, pumps, valves, and other metal components, resulting in fouling, corrosion, and degradation. Some of the common chemicals used in closed loop and building services treatments include corrosion inhibitors, scale inhibitors, biocides, and pH adjusters.
Corrosion inhibitors are used to form a protective layer on metal surfaces and prevent the formation of corrosion products, which can reduce the efficiency and lifespan of the system. Scale inhibitors are used to prevent the precipitation of minerals, such as calcium and magnesium, which can cause scale buildup and reduce water flow. Biocides are used to prevent the growth of bacteria, algae, and fungi, which can cause biofilm formation and system deterioration. pH adjusters are used to maintain the pH of water and prevent acid corrosion.
Conclusion
Water treatment chemicals are essential for maintaining the quality and safety of water for human consumption and industrial uses. They play a vital role in reducing the impact of effluents on the environment and improving the efficiency and lifespan of water systems.
