    With the improvement of people's living standards, production activities are frequent, and the amount of garbage discharged is also increasing. The problem of water treatment has gradually attracted everyone's attention. However, there are various problems in the water treatment process. The foam is one of them. It not only causes serious pollution of the external environment, but also slows down the process and affects the active mud and bacteria. But don't worry, Zilibon can easily solve this problem with a special water treatment defoamer.


    So how does the foam produce during the water treatment?

    1.Sludge residence time

    The activated sludge process using the delayed aeration method is more prone to foaming. In addition, once the foam is formed, the biological residence time of the foam layer is independent of the sludge residence time in the aeration tank, and it is easy to form a stable and durable foam.

    2.pH value

    Changes in pH can also cause incompatibility of the activated sludge, resulting in a foaming phenomenon.

    3. Dissolved oxygen

    When the dissolved oxygen is insufficient and the system is operated at a low load,which will easily to generate the denitrifying foam.

    4. Aeration method

    The bubbles generated by different aeration modes are different, and the microbubbles or small bubbles are more favorable for producing biofoam than the large bubbles, and the foam layer is easily concentrated in a region with low aeration intensity.

    5. Temperature

    The fungi associated with the formation of biofoam have their own suitable growth temperature and optimum temperature. When the environment or water temperature is favorable for the growth of fungi, foaming may occur.

     Annoying bubbles in the water treatment process, are you stuck in this trobule?

    (the foam problem in water treatment)

    The principle of action of water treatment defoamer as follow:

    1.Breaking effect

    Mainly for liquid foams, the antifoaming agent mainly causes the foam to be ruptured by adsorbing the surface tension of the foam to make the foam thin.

    2. Antifoaming effect

    It is to reduce the generation of foam by destroying the generation of foam, which can effectively prevent the formation of liquid bubbles;

    3. Defoaming

    Invading the bubble from the interface of the bubble, the air that collects the bubble in the liquid forms a large bubble, which becomes larger due to buoyancy, floats out of the liquid surface, and promotes the defoaming effect.


    Zilibon is a manufacturer with 16 years of application experience. It has far more defoaming technology than other antifoaming agents in the market. 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.
