The industrial sewage treatment defoamer developed and designed by Nanhui defoamer manufacturer is a concentrated formula defoamer composed of modified silicone polyether, polyether, and organic silicon. It can be used in shield sewage and urban Sewage, direct discharge sewage, chemical sewage, industrial waste water, sand washing plant sewage treatment, power plant sewage and other processes. The following editor briefly introduces the reasons why industrial sewage is prone to foaming.

Sewage treatment process is easy to cause foaming problem
Industry will inevitably produce a large amount of waste water. The waste water contains oils, suspended solids, heavy metals, and other harmful substances and foams. Direct discharge will pollute the surrounding environment. The Environmental Protection Monitoring Bureau has high requirements for sewage treatment and strict testing. The sewage treatment process is complicated, and it is easy to encounter foam problems during the treatment process. Sewage foam is mainly related to the following reasons:
Aeration tank foam
In the initial stage of the aeration tank, the sludge is relatively small and the sludge load is high, and foam is prone to occur at this time. And at the initial stage of the activated sludge process operation, because the sewage contains some surface active substances, it is easy to cause surface foam;
Surfactant foaming
Because the sewage contains surfactant substances, it causes foaming. The composition of sewage is complex, including oil, starch, protein, such surface active substances and harmful substances, which can easily cause foam to breed;
The organic matter load and nitrogen and phosphorus content are too high
Generally, sewage contains organic matter, nitrogen and phosphorus, and other substances added in the water treatment process are easy to react, so it is easy to produce a lot of foam.

Sewage treatment defoamer has a good effect on the plan
Sewage treatment does not matter whether it is the foam caused by the water quality component or the foam caused by the treatment process. Any untimely treatment will bring negative impacts, adversely affect the treatment system, and affect the discharge of water quality. To solve the problem of foam in sewage, adding water treatment defoamer is a good way. Moreover, the treated sewage has the economic value of recycling, which is beneficial to environmental protection, reduces the cost of sewage treatment, and improves work efficiency.
