Foam problems in water treatment！

Water treatment is a crucial aspect in modern industrial production. However, the foam problem often becomes a key factor in restricting the efficiency and quality of water treatment. When the environmental protection department detects excessive foam and does not meet the discharge standard, direct discharge not only slows down the process, but also may cause potential harm to the environment. In order to solve this problem, the application of defoamer is particularly important.

Hazards of Foam

Excessive foam overflowing from the surface of the treatment facility not only affects the normal operation of the facility, but also may cause pollution to the surrounding environment. Through the use of defoamers, the foam can be effectively controlled to protect the cleanliness and safety of the environment.

The accumulation of foam during aeration or oxygenation in biological water treatment can interfere with the treatment progress and even lead to the loss of activated sludge and bacteria. The application of defoamers can reduce the generation of foam and ensure the smooth progress of the biological water treatment process.

Excessive foam in the circulating water not only affects the secondary utilization of water, but also may have a direct impact on production progress and product quality. The use of defoamers can reduce the foam in the circulating water, ensuring water quality and production efficiency.

How to choose defoamer

The principle of action of defoamers is mainly through a chemical interaction with the surfactant in the foam, which in turn reduces the activity of the surfactant, in order to promote the rupture of the foam. In fact, some defoamers may also change the surface structure of the foam or reduce the stability of the foam to achieve the effect of defoaming. Defoamers are undoubtedly a good solution when faced with a large number of foam problems.

When choosing an antifoam agent, you also need to pay attention to its effect. Some defoamers may have incomplete defoaming or secondary foam problems, which not only can not solve the foam problem, but also may introduce new problems. It should be noted that some defoamers may be harmful to biological bacteria, affecting the MBR system, and even destroying the percolation membrane and blocking the ultrafiltration membrane. After adding defoamer, you also need to pay attention to its effect on water quality indicators, such as pH value, total organic carbon, etc. If these indicators exceed the standard, it may trigger secondary pollution and affect the effect of water treatment. .When choosing an antifoam agent, you need to ensure that it will not cause damage to the water treatment system. Therefore, cost and ease of operation are also factors to be considered when selecting defoamers.
