What are the types of water treatment defoamer agent?

Water treatment defoamer is a chemical used to remove foam from water. With the continuous development of industrialization and urbanization, water pollution problems have become increasingly prominent, and water treatment defoamer agents have become more and more important. The following will introduce several common classifications of water treatment defoamer agents.

1. According to the properties of defoamer agent

It can be divided into organic defoamer and inorganic defoamer. Organic defoamer are made of organic compounds. Common organic defoamer include surfactants, polymers, etc. Inorganic defoamer is made of inorganic compounds, such as silane defoamer.

2. According to the mechanism of action of defoamer

It can be divided into surfactant defoamer and physical defoamer. Surfactant-type defoamer agents destroy the stability of the foam by changing the surface tension of the liquid, thereby achieving the defoamer effect. Physical defoamer agent, on the other hand, prevent the formation and aggregation of bubbles by forming a thin film at the foam-liquid interface, thereby reducing foam generation.

3. According to the use of defoamer

It can also be divided into industrial defoamer and domestic defoamer. Industrial water treatment defoamer agent are mainly used in water treatment in industrial production processes, such as petrochemical,papermaking,textile,food processing and other fields.Domestic water treatment defoamer agent are mainly used in aquaculture and aeration tanks, such as aquaculture sewage, aeration tank wastewater, etc.

It should be noted that when using water treatment defoamer agent,the appropriate defoaming agent should be selected according to the specific application scenarios and needs. Different defoaming agents have different chemical compositions and mechanisms of action, so they need to be adjusted and controlled according to specific conditions when used to achieve the best defoaming effect.

In short, water treatment defoamer agent can be divided into many types according to their properties, mechanisms of action and uses. Understanding these classifications helps us better select and apply defoamer agent,thereby improving the effectiveness of water treatment and protecting the environment and human health.
