How does a water treatment defoamer work?

The principle of action of water treatment defoamer mainly achieves the defoaming effect through the following aspects:

1.Reduce surface tension: The surfactant or polymer component in the defoamer can reduce the surface tension of the liquid, so that the interfacial tension between the bubble and the foam is reduced, so that the bubble bursts, and the purpose of defoaming is achieved.

2.Antifoam: The ingredients in the defoamer can invade the inside of the foam and inhibit the formation of foam. By inhibiting the generation of foam, the defoamer can effectively reduce the generation of foam during the water treatment process and ensure the water treatment effect.

3.Destruction of the foam structure: Defoamers can penetrate into the foam and loosen the foam structure, which can cause the foam to burst. This action helps to eliminate foam that has already been created and prevents it from forming again.

4.Improved water quality: Some components in water treatment defoamers have the ability to adsorb dissolved oxygen in water, thereby slowing down metal oxygen corrosion. In addition, defoamers can also adsorb organic matter and microorganisms in the water, helping to improve water quality.

5.Stability: Defoamers have a certain degree of stability and can maintain the defoaming effect for a long time. This allows the defoamer to continue to work during the water treatment process, ensuring that the water treatment is not affected by foam.

In short, the principle of action of water treatment defoamer is to achieve defoaming effect by reducing surface tension, inhibiting foam formation, destroying foam structure, improving water quality and maintaining stability, so as to ensure the normal operation of water treatment process.

Water treatment defoamer by adsorbing the surface tension of the foam, making the foam thinner and causing the foam to burst, by destroying the generation of foam, so that the foam generation is reduced, can effectively prevent the generation of liquid bubbles, invade the bubbles from the interface of the bubbles, gather the air of the bubbles in the liquid to form a large bubble, due to the buoyancy effect becomes larger, the liquid surface is raised, and the deaeration is promoted.

Moreover, the use of water treatment defoamer will not affect the basic properties of the foaming system, will not harm the microorganisms in the water, and will not affect the progress of water treatment, water quality index detection and discharge.

Defoamers generally perform defoaming and foam suppression by reducing the surface activity of the treated substance, and when the defoamer is sprinkled in the foam, it comes into contact with the foam surface, and its surface tension decreases, resulting in the breakage of the thin layer.

Water treatment defoamer changes the surface tension by adsorbing foam, makes the foam thinner and causes the foam to burst, and reduces the foam generation by destroying the production of foam, which can effectively prevent the generation of liquid bubbles, invade the bubbles from the interface of the bubbles, and gather the air of the bubbles in the liquid to form a large bubble, which becomes larger due to the buoyancy and floats the liquid surface, which promotes the deaeration effect.

Foam problems in the water treatment process will affect the normal operation, so defoamers are generally used, depending on your specific requirements.

Hello, the water treatment defoamer is added directly to the foaming system during water treatment foaming to ensure that it is evenly dispersed. If diluted, do not store the dilution for more than 8 hours. For the system with a high foaming temperature (>60), it is recommended to add it to the system before 60 and disperse evenly to exert its maximum effectiveness.

According to the viscosity, temperature and stirring of different foaming systems, the more economical dosage is selected in units of 10ppm, and generally speaking, the dosage of 30-200ppm can ensure the ideal defoaming effect.

During water treatment, some wastewater aerobic pools will produce a large amount of foam, especially in winter, when it is serious, it will overflow the pool, and the foam produced is white and yellow, the white foam is generally caused by the high content of ammonia nitrogen in the wastewater, and the yellow foam is generally caused by a bacterium (the specific name is forgotten), and the influence of the foam is often eliminated by defoamers. The defoamer has fast defoaming speed and long-lasting foam inhibition, and is used in a variety of foaming systems such as pharmaceutical, papermaking, leather, printing and dyeing, municipal sewage biological treatment process and chemical cleaning.

4.It is non-physiotoxic and has no compound effect on the use system.

5.It has both anti-foaming and anti-foaming effects, and the foaming inhibition time can reach more than 48 hours.

Water treatment defoamer is specially developed for the problem of Pipei foam in the water treatment process, which is targeted. The defoaming effect is very good, the defoaming speed is fast, and the foaming inhibition time is long; The water solubility is good, and when added to water, Jian Huizhao will not affect pH, iron content, total alkalinity, total phosphorus, total calcium and magnesium and other indicators, and will not change the appearance and color; It will not cause harm to biological bacteria, will not affect the MBR system and the permeable membrane, has good dispersibility, and will not clog the filter membrane.

Water treatment defoamer is suitable for all kinds of circulating sewage treatment, industrial sewage, circulating wastewater treatment in various industries, seawater treatment, factory sewage, domestic water, rent-off production water or dischargeable wastewater treatment defoaming, such as industrial papermaking, textile printing and dyeing, electroplating, oilfield, mining defoaming, etc. It is characterized by alkali and acid resistance, fast defoaming speed, long foam inhibition time, high efficiency, strong versatility, low COD, low consumption and low cost.

Water treatment defoamer is mainly used to reduce the surface tension in the water, break the bubbles in the water before or inhibit the water, so as to achieve the effect of defoaming. The following are the main defoaming effects of water treatment defoamers:

1.Burst bubbles: After adding an appropriate amount of defoamer to the water, the surface tension of the water can be reduced, and the bubbles can be quickly burst and disappear, thus preventing the bubbles from forming and floating in the water.

2.Inhibition of bubbles: Some water contains gases such as air, oxygen, and carbon dioxide that are soluble in water, and these gases tend to form bubbles in the water. Defoamers can reduce the surface tension of these gases, slowing down their diffusion and accumulation in water, thereby inhibiting the formation of bubbles.

3.Energy Saving: Air bubbles in water can cause problems such as pressure loss and poor heat transfer in pipes, equipment and systems, resulting in wasted energy and equipment damage.

Defoamers can effectively reduce the number and size of bubbles in water, reduce pressure loss and poor heat transfer, and improve the operating efficiency and energy saving effect of the system.

4.Improving water quality: During water production, transportation, and treatment, air bubbles can affect water clarity, clarity, and purification effectiveness. Defoamers can effectively remove air bubbles and improve the quality and stability of water.

It should be noted that different types of water treatment defoamers have different scope and use methods, so when choosing a defoamer, it is necessary to select the appropriate type and use method of defoamer according to the specific conditions and use requirements of water, and operate in accordance with the instructions for use.

The defoamer for water treatment is more evenly dispersed during use, and it relies on a non-ionic medium to dilute the bubbles and eliminate them.

The defoamer has the effect of defoaming and inhibiting foam in socks. When the defoamer is evenly sprinkled in the foam, it touches the surface of the foam and its surface tension decreases, causing the thin layer to burst quickly.

The working principle of defoamers mainly involves changing the surface properties of a liquid to control and eliminate air bubbles or foam. The specific working principle can vary depending on the type and nature of the defoamer, and here are a few common working principles:

1.Reduces surface tension: Antifoam vibrators can reduce the surface tension of liquids, making bubbles less likely to form or burst.

Surface tension is the interaction force between the molecules of a liquid that determines the degree of tension on the surface of the liquid. By reducing the surface tension, the defoamer can reduce the stability of the bubbles, making them susceptible to bursting or preventing the formation of bubbles.

2.Diffusion to the surface of the bubble: The defoamer can diffuse to the surface of the bubble, forming a thin film on the surface.

This sail hits the late layer film to change the physical and chemical properties of the bubble surface, making the bubble unstable. The film can increase the surface tension of the bubble, causing it to burst; Or change the interaction of the bubbles with the surrounding liquid, causing them to aggregate and dissipate.

3.Prevents bubble polymerization and diffusion: Some defoamers can form polymer or colloidal particles in liquids that can adsorb on the surface of bubbles, preventing the polymerization and diffusion of bubbles.

This effect can be achieved by forming a physical barrier on the surface of the bubble or through a chemical reaction.

4.Destruction of foam structure: Some defoamers cause the foam to disintegrate quickly by destroying the structure inside the foam. This defoamer usually changes the pH of the liquid or adds chemicals that react with the components in the foam, causing the foam to collapse.

In summary, the working principle of defoamers can be achieved by reducing surface tension, forming thin films, preventing bubble polymerization and diffusion, and destroying the foam structure. The exact principle of operation will vary depending on the type of defoamer, its composition, and the environment in which it is being applied. Choosing the right defoamer needs to consider the nature of the liquid, application needs, and environmental factors, as well as the advice of professionals.

The defoamer acts during or after the formation stage of the thin layer of the Sakura foam, and the evenly dispersed defoamer penetrates into the foam elastic membrane and is distributed in the membrane, causing the thin layer to break through the reduction of surface tension.

The evenly dispersed defoamer penetrates into the thin layer of foam and forms a monomolecular film, which reduces its adhesion and makes it easy for the thin layer to break.

Defoamers containing hydrophobic particles have a third machine implicit preparation. These hydrophobic particles reach the surface of the thin layer and adsorb surfactants at the top of the thin layer. The thin layer breaks due to the absence of surfactant.

Generation of bubbles in paints:

In the production process of coatings, air will be drawn into the air and bubbles will be formed, and some raw materials in the coating, such as surfactants, dispersants, etc., will stabilize the bubbles.

Air bubbles can also be generated during the application of the paint, depending on how the paint is applied. For example, curtain coating can continuously involve air in the paint, airless spraying can easily involve empty stove ear gas, and spraying under relatively low humidity conditions or high temperature conditions is easy to produce bubbles.

The working principle of the defoamer is to reduce the surface tension and activity of the blistering page, so as to achieve the effect of defoamer and foam inhibition.

The main working principle of the defoamer is to penetrate into the foam bullet film and diffuse in it, and then reduce the surface tension of the foam surface so that the foam dissipates and inhibits. Qin Qiaohe.
