I think we all know that water is our source of life, and when we are in industrial production and all kinds of sewage in the discharge process, all need to carry out water treatment, which can effectively remove some harmful impurities in the water, but in this process will also appear from time to time a large number of foam problems, and engaged in water treatment industry personnel know that this time often needs to use defoamer for water treatment to solve the problem.
The emergence of water treatment foam and its hazards
1. In the water treatment pool production of a large number of foam, and these bubbles will slowly accumulate into a foam layer, the height of these foam layers can reach a meter high, and because this sewage with pigments, suspended solids, ammonia, and nitrogen elements, but also because of the ph value of water quality changes and foam overflow will cause radiation pollution of the surrounding water quality, thereby exacerbating the problem of environmental pollution, and the foam is very light. At this time, a little wind at will can make the foam fly.
2. In the water treatment system there are some impurities such as oil and lipid substances, such substances are not only difficult to remove, but these substances will also produce a large number of Nocardia, a large number of reproduction, which will appear on the surface of the water treatment system a layer of white foam.
3. Because the water treatment system of chemical additives, industrial impurities are complex and diverse, and there are many toxic components and other characteristics, which leads to the emergence of foam size vary, foam viscosity is large, large bubble shape is generally stretched into an ellipse, foam stability is high and not easy to break.
The role of defoamer for water treatment
Water treatment defoamer's wider ph value can be well adapted to the foam in these water treatment systems, and because of its chemical stability it does not appear in the use of process is not easy to break the emulsion and lose defoaming activity, stable defoaming in acid and alkali salt wastewater, does not affect the water treatment discharge standards. And this water treatment defoamer permeability, dispersion and it's more than surface tension can greatly reduce the tension of the foam film in fact lose vitality, while allowing its stability to reduce, prompting foam discharge, so as to achieve the role of defoaming.
