Application of Defoamers in Industrial Water Treatment
In the field of water treatment, defoamers are widely used, and their performance characteristics are very prominent. Its biggest feature is defoaming and foam suppression. But how much do people know about its application in the field of industrial water treatment? Let’s listen to what industry experts say.
1. Defoamers are one of the important agents in water quality stabilizers and have been widely used in industrial circulating cooling water, boiler water and wastewater treatment. In the process of industrial water treatment, due to the different physical and chemical properties, varieties and dosages of the agents used and the different composition, temperature, pressure, pH value, flow rate and dissolved gases in the water, a large amount of foam is often generated, which seriously affects the water treatment effect.
2. The advantages and disadvantages of foam
According to industry experts engaged in the research and development and production of water-based defoamers, there are various colorful and dazzling bubbles in nature. Sometimes foam is very useful in industrial and agricultural production and life, such as mineral flotation and processing, the manufacture of foam plastics and foam rubber, beverage and food processing, foam fire extinguishing agents, etc., which require excellent foaming agents. However, sometimes foam is very harmful to industrial and agricultural production, such as metal corrosion protection, textile printing and dyeing, papermaking, brewing and other industries and industrial water treatment processes, which often require various defoaming agents for defoaming.
3. Types of foam and defoaming methods
In the thin wall surrounded by liquid or solid, there are various gas microparticles, called bubbles. Many bubbles gather together to form a screen wall called foam. There are many types of foam, such as liquid foam, elastic foam, solid foam, liquid-solid foam and emulsion foam. In industrial water treatment, physical and chemical methods are mainly used for defoaming.
4. Mechanism of action of defoaming agent
The bubbles in the liquid are divided into three forms: bubbles, foam and dispersed gas saturation. Bubbles are mainly affected by two factors: the foaming power and stability of water.+
