Water treatment agent is a general term for a class of chemical agents used in water treatment. It is widely used in petroleum, chemical, metallurgy, transportation, light industry, textile and other industrial sectors. The water treatment agent includes a corrosion inhibitor, a scale inhibitor, a bactericide, a flocculant, a purifying agent, a cleaning agent, a pre-filming agent, and the like. In practical applications, it is often used as a water treatment agent for a composite formulation, or a combination of various water treatment agents. Therefore, it is necessary to pay attention to the antagonistic effects between the components due to improper compounding, so that the effect is reduced or lost, and the synergistic effect (the synergistic effect produced by the coexistence of several agents) is also fully utilized to increase the efficiency. In addition, most water treatment systems are open systems with a certain amount of emissions, taking into account the environmental impact of various water treatment agents.
Common water treatment agents are: flocculant, ferrous sulfate heptahydrate, polymeric iron salt, calcium hydroxide, ferric chloride hexahydrate, bactericidal algaecide, chlorine dioxide, scale inhibitor, polyacrylamide ( Cationic, anionic, nonionic), polyaluminum chloride, polyaluminum ferric chloride, ferrous sulfate, and the like.
Water treatment agent is one of the most widely used and most widely used special products in the water industry, pollution control and water-saving treatment technology, including flocculants, scale inhibitors, corrosion inhibitors, biocides, etc. It removes suspended solids and toxic substances in water, controls the formation of scale and sludge, reduces corrosion of water contact materials, deodorizes bacteria, decolorizes, softens, stabilizes water quality and seawater.
