Water treatment agent (water treatment agent) is a general term for chemical agents used in water treatment. It is widely used in petroleum, chemical industry, metallurgy, transportation, light industry, textile and other industrial sectors. Water treatment agents include corrosion inhibitors, scale inhibitors, fungicides, flocculants, purifiers, cleaning agents, pre-film agents, etc. In practical applications, water treatment agents with compound formulations are often used or various water treatment agents are synthetically applied. Therefore, we should not only pay attention to the antagonism between the components due to inappropriate compounding, so as to reduce or lose the effect, but also make full use of the synergistic effect (synergistic effect produced by the coexistence of several medicines) to increase the efficiency. In addition, most water treatment systems are open systems, there will be a certain amount of emissions, use to take into account the impact of various water treatment agents on the environment.


Common water treatment agents are: flocculant, ferrous sulfate heptahydrate, polyferric salt, calcium hydroxide, ferric chloride hexahydrate, bactericide and algaecide, chlorine dioxide, scale and corrosion inhibitor, polyacrylamide (cationic, anionic, non-ionic), polyaluminium chloride, polyaluminium ferric chloride, ferrous sulfate, etc.


Water treatment agent is one of the most widely used and consumed special products in water industry, pollution control and water-saving reuse engineering technology, including flocculants, scale inhibitors, dispersants, corrosion inhibitors, biocides and so on. It is mainly used to remove suspended solids and toxic substances in water, control the formation of scale and sludge, reduce the corrosion of water contact materials, deodorize and sterilize. Decolorization, softening, stabilization of water quality and seawater.
