What is water treatment agent?

I have a French customer who once wanted to engage in the import business of a water treatment agent because he thought the product was very versatile and profitable. But he did not understand what is water treatment agent, water treatment agents are what kinds, so it is difficult to make a decision in the end to import what kind of water treatment agent products, so what is water treatment agent?

Water treatment agent is to remove most of the harmful substances in the water (such as corrosives, metal ions, dirt, and microorganisms, etc.). Water treatment agent is a general term for a class of chemical agents used in water treatment, widely used in petroleum, chemical, metallurgical, transportation, light industry, textile, and other industrial sectors. Water treatment agents include corrosion inhibitors, scale inhibitors, biocides, flocculants, purifiers, cleaning agents, pre-film agents, etc.

Do you still want to know the common types and uses of water treatment agents?

Common water treatment agents include flocculants, ferrous sulfate heptahydrate, polymeric iron salts, calcium hydroxide, ferric chloride hexahydrate, algaecide, chlorine dioxide, scale and corrosion inhibitors, polyacrylamide (cationic, anionic, nonionic), polymeric aluminum chloride, polymeric ferric aluminum chloride, ferrous sulfate, etc.

  • Corrosion inhibitor

In water treatment, commonly used passivation film-type corrosion inhibitors such as chromate, nitrite, molybdate, etc.; commonly used precipitation film-type corrosion inhibitors such as polymeric phosphate, zinc salt, etc.; commonly used adsorption film-type corrosion inhibitors such as organic amines, etc.

  • Scale inhibitor

There are two types of organic and polymeric scale inhibitors used in water treatment: ① organic phosphonic acid such as EDTMPS (ethylenediamine tetramethylene phosphonic acid), HEDP (hydroxyethylenebisphosphonic acid), etc.; ② polycarboxylic acid, such as polyacrylate, hydrolyzed polymaleic anhydride, etc.

  • Bactericides

Quaternary ammonium salts such as dodecyldimethylbenzylammonium chloride or dodecyldimethylbenzylammonium bromide, etc., often both bactericidal, stripping, corrosion inhibition, etc., have a promising development and are now used in oilfield water, industrial cooling water, etc.

  • Flocculant

Anionic flocculants, such as carboxymethyl cellulose, sodium polyacrylate, etc.; cationic flocculants, such as polyethylene amine, etc.; and non-ionic flocculants, such as polyacrylamide, etc.

  • Purifying agent

In addition to general flocculants such as aluminum salts, polyacrylamide, etc., these purifying agents often contain some surfactants.

  • Cleaning agent

Sulfosuccinic acid bis(α-Ethylhexyl ester) sodium salt is a surfactant used as a special cleaning agent for cleaning impurities such as oil and floating rust on metal surfaces.

  • Pre-film agent

Commonly used pre-film agents are sodium hexametaphosphate plus zinc salt, sodium tripolyphosphate, etc.

  • Auxiliary agents

In order to better play the efficacy of water treatment agents, but also need a series of water treatment agents used in conjunction with the agent, such as cleaning agents, defoamers, deaerators, oil flotation agents, pre-film agents, etc.


Sincere Chemical has been committed to the research and development of environmental protection water treatment chemicals and the reform of production process for more than ten years and has achieved a number of continuous, large-scale, and intelligent manufacturing technologies of water treatment agents and related fine chemicals with independent intellectual property rights. More than ten automated production workshops have produced hundreds of varieties of many series required by the industry, including scale inhibitors, corrosion inhibitors, algaecides, chelating agents, dispersants, reverse osmosis agents, auxiliary detergents, etc., totaling more than 300,000 tons. Welcome customers in need to consult the products and technical knowledge of water treatment agents.
