Wastewater treatment industry how to choose the right defoamer
Colorful foam can bring us much joy, however, in industry, foam generation is not always welcome as it can lead to reduced yields and affect the quality of the finished product. Water treatment has always been a major problem for major industries, and one of the headaches is foam. The emergence of foam will make a large number of microorganisms in the water body die, affecting the water quality, which leads to substandard wastewater discharges, affecting the subsequent industrial processes, resulting in pollution of the environment.
In order to eliminate these harmful foams, sewage treatment defoamer has been favored by many manufacturers, and its application has become more widespread.
First of all, let's understand the main components and the principle of action of sewage treatment defoamer. Foam in sewage is mainly caused by organic matter and surfactants. The active substances in the sewage treatment antifoam agent can have a chemical reaction with these organic substances and surfactants, destroying the surface tension of the foam and making it disappear quickly. In the use of sewage treatment defoamer, need to pay attention to the following points:
Determine the scope of application of the sewage treatment defoamer:
Different sewage treatment defoamer is suitable for different types of foam, such as organic foam, inorganic foam and so on. Therefore, when choosing an antifoam agent, it is necessary to determine its scope of application according to the actual situation.
2. Determine the dosage of sewage treatment defoamer:
The dosage of antifoam agent for sewage treatment should be determined according to the severity of the foam and the capacity of the treatment equipment. Generally speaking, the initial dosage can be initially estimated according to the empirical value, and then adjusted appropriately according to the actual effect.
3. Pay attention to the way of adding sewage treatment defoamer:
Sewage treatment defoamer can be added by directly adding to the sewage or by spraying. In the process of adding, should ensure that the antifoaming agent is evenly distributed, and avoid excessive addition.
4. Pay attention to the mixing time of the sewage treatment defoamer:
The mixing time of the sewage treatment defoamer should be controlled according to the actual situation. Generally speaking, the mixing time should not be too long, so as not to cause a decline in the treatment effect.
5. Regularly check the effect of sewage treatment defoamer:
The effect of sewage treatment defoamer may be affected by sewage water quality, temperature and other factors. Therefore, it is necessary to check the treatment effect regularly and make appropriate adjustments according to the actual situation.
In addition to the use of wastewater treatment defoamer, we should also focus on reducing the generation of foam from the source. Strengthening sewage pretreatment and reducing the content of organic matter and surfactants can effectively reduce the generation of foam. In short, the sewage treatment defoamer is a kind of chemical substance that effectively solves the foam problem in the sewage treatment process. When using it, we should choose the applicable defoamer according to the actual situation, and master the appropriate dosage and use method, in order to improve the treatment effect and protect the environment. At the same time, we should focus on reducing the generation of foam from the source to realize sustainable sewage treatment.
