    In the sewage treatment process, aeration tanks, as a key link, often encounter foam problems. These foams not only affect the normal operation of the aeration tank, but may also have adverse effects on the environment. In order to solve this problem, aeration tank defoamers came into being and became an indispensable part of the water treatment system.

    how to control foaming in aeration tank


    Causes and hazards of aeration tank foam


    The foam in the aeration tank is mainly caused by organic matter, surfactants and other substances. These substances produce a large amount of foam due to the action of oxygen during the aeration process. If these foams are not handled in time, they will lead to a series of problems:


    Reduce aeration efficiency: Foam covers the surface of the aerator, hindering oxygen transfer and reducing aeration efficiency.


    Affect biological reactions: Foam may carry pathogens, microorganisms, etc., which have an adverse effect on the biological reaction process.


    Environmental pollution: Foam overflow may cause environmental pollution and affect the surrounding ecological environment.


    The role and characteristics of aeration tank defoamers


    Rapid defoaming: Defoamers can quickly penetrate foam, destroy its stability, and make the foam disappear quickly.


    Improve aeration efficiency: After eliminating the foam, oxygen transfer is smoother, improving aeration efficiency.


    Environmentally friendly and harmless: The defoamer adopts an environmentally friendly formula, which is harmless to the environment and will not affect the surrounding ecological environment.


    Usage and precautions of aeration tank defoamer


    Use correctly according to the instructions: According to the type and concentration of the defoamer, use it correctly according to the instructions to avoid excessive or insufficient use.


    Regular inspection: Regularly check the foam situation in the aeration tank and add defoamer in time.


    Safe storage: The defoamer should be stored in a cool, dry and ventilated place, avoiding direct sunlight and high temperature.


    In short, the aeration tank defoamer is an important tool for maintaining the normal operation of the water treatment system. By using a defoamer, the foam in the aeration tank can be quickly eliminated, the aeration efficiency can be improved, and the environment can be protected. During use, attention should be paid to safe storage and correct use methods to ensure its effectiveness and safety.
