    Water is an indispensable part of people's daily life. Whether it is factory production or family, office, water consumption is increasing. The mineral water and pure water that we drink in our life must pass the membrane separation technology of reverse osmosis. Its filtration precision reaches 0.0001um, which can remove more than 97% of dissolved solids in raw water. Since the water itself contains surface active components during the reverse osmosis water treatment process, when the continuous reverse osmosis water system is operated, the air introduced by the agitation will cause a large amount of foam to be generated, resulting in a decrease in the performance of the reverse osmosis membrane, deposition of the membrane surface and growth of microorganisms. Microorganisms not only block the membrane, but also have an erosive effect on cellulose acetate. At this time, it is suggested to add a proper amount of reverse osmosis water treatment defoamer in order to affect the efficiency of the equipment and the quality of water treatment.


    Reverse osmosis water treatment defoamer is mainly produced by special process using the characteristics of polyether aliphatic products, which belongs to silicon-free products. This defoamer is different from organosilicon defoamer. It is a highly effective defoamer specially developed to solve various biological water treatment systems. This defoamer has many excellent characteristics, such as fast defoaming speed, long antifoaming time, high defoaming efficiency, low dosage, non-toxic, non-corrosive, no side effects on various aquatic fungi, environmental protection and so on. Reverse osmosis water treatment defoamer is easy to disperse in water, has good compatibility with liquid, and will not destroy the emulsified oil slick.

    (Characteristics of Defoamer for Reverse Osmosis Water Treatment)

    In addition, reverse osmosis water treatment defoamer also has product characteristics:

    1. Low surface tension, high activity and strong defoaming power.

    2. No change in heat resistance and high temperature, low volatility.

    3. It has good chemical stability, chemical inertia, no reaction with other substances, and can be used under harsh conditions.

    4. Impurities in water are removed quickly.

    5. It has both antifoaming and antifoaming effects, and the antifoaming time can reach more than 48 hours.


    Zilibon is a manufacturer with 16 years of application experience. It has far more defoaming technology than other antifoaming agents in the market. From the above cases, we prove the strength of our Zilibon defoamer. We have a group of excellent defoaming engineers, and An independent laboratory that facilitates defoaming experiments with foams that are difficult for customers to solve.
