Wastewater treatment defoamer, how much do you know?
What? You still don't know how to solve the wastewater foam problem? The following will take you to solve the problem of wastewater foam. I think we will have a lot of foam problems from time to time in the discharge or treatment of wastewater, and the appearance of foam will also bring us a lot of trouble, then we often need to use defoamer to solve the problem of foam, but there are a wide range of wastewater treatment defoamer, and want to pick the right wastewater treatment defoamer partners can continue to look down.
1. Alcohol wastewater treatment defoamer
This type of wastewater treatment defoamer is mainly used to eliminate the foam that appears in the production process of paper industry. This kind of foam is mainly composed of lignin, cellulose, volatile organic acids, etc. This kind of wastewater has the characteristics of large emissions, difficult to degrade, high foam concentration, poor biochemical properties, etc. This kind of wastewater is also one of the more difficult to treat industrial wastewater. The alcohol wastewater treatment defoamer is developed for its foam characteristics, defoamer has strong acid and alkali resistance, not easy to break the emulsion, oil bleaching, can be stable in the paper wastewater fast defoaming and other characteristics.
2. Polyether wastewater defoamer
This kind of wastewater treatment defoamer has high transparency, mainly used in some wastewater treatment industry with high requirements for process, such as food industry wastewater, pesticide wastewater, wastewater containing cyanide, wastewater containing phenol, heavy metal wastewater, etc. These wastewater industries will need to use defoamer to solve our foam problem. And the amount of defoamer added is generally 0.025-0.25%, and the chemical properties of such wastewater treatment defoamer are stable and good, so the beneficial colonies in the wastewater will not be destroyed. Therefore, more in line with the current green concept, at the same time, this type of defoamer also has a strong surface activity, can effectively adsorb a variety of large bubble micro bubble, not only fast defoaming, more can play a long time foam inhibition function, defoaming performance excellent characteristics.
3. Silicone wastewater defoamer
This type of wastewater treatment defoamer can be used to solve the foam problem of power plant desulfurization wastewater, chemical industry wastewater, printing and dyeing industry wastewater, dye production wastewater, food industry wastewater and other industries, while this type of defoamer is also the most widely used in these three defoamers. The amount of silicone defoamer is generally 0.05-2%, the manufacturing cost is low, but the defoaming effect in the wastewater treatment industry is really "a great", diffusion permeability, so defoaming more quickly and cleanly, do not leave residues.
