Application Field of Water Treatment Agent

2020-11-18

Everyone in the field of environmental protection water treatment knows how important the water treatment agent is, and we can use it to achieve the indicators that the biological treatment link cannot reach.

Water treatment agent is a general term for a class of chemical agents used in water treatment, which is widely used in petroleum, chemical, metallurgy, transportation, light industry, textile and other industrial sectors. In practical applications, complex formulations of water treatment agents are often used, or various water treatment agents are combined. Therefore, it is necessary to pay attention to the antagonism between the components due to improper compounding, reducing or losing the effect, and also to make full use of the synergistic effect (the synergistic effect produced when several drugs coexist) to increase the effect. In addition, most water treatment systems are open systems and will have a certain amount of discharge. When using, consider the impact of various water treatment agents on the environment.

Its application areas involve industrial water, municipal/drinking water treatment, sewage and wastewater treatment and seawater desalination.

In the field of industrial water, it is mainly used in industrial circulating water treatment and industrial boiler water treatment. The chemicals used in industrial circulating water treatment mainly include scale inhibitors, corrosion inhibitors, bactericidal algaecides, cleaning agents, and pre-filming agents. Commonly used methods of industrial boiler water treatment are out-of-boiler water treatment and in-boiler water treatment. The main chemicals used are: corrosion and scale inhibitors, deoxidizers, water supply alkali reducers, ion exchangers, regenerating agents, softeners, alkalis Degree regulators, detergents, etc.

The water treatment chemicals involved in municipal/drinking water treatment generally include: bactericidal and algaecide, flocculant, corrosion inhibitor, etc.

The water treatment chemicals involved in sewage treatment generally include flocculants, sludge dehydrating agents, defoamers, chelating agents, and decolorizing agents.

The mainstream technologies for seawater desalination include distillation and membrane methods. The membrane is easy to be blocked in use, so it is necessary to add scale inhibitors, detergents, flocculants, scale inhibitors and dispersants to the water. The distillation method is easy to produce scales and reduce the evaporation efficiency. You can add polyphosphate, organic phosphoric acid, phosphine-based polycarboxylic acid, etc. to the raw water to soften the water, and chelate calcium, magnesium ions and other metal ions to make it difficult to precipitate, prevent the formation of scale.
