Dispersant is a kind of interfacial active agent that has both opposite properties of lipophilicity and hydrophilicity within the molecule. It can uniformly disperse solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquids, while also preventing particle sedimentation and condensation, forming amphiphilic reagents required for stable suspensions

      Congo Republic of the Congo Defoaming agents for electroplating wastewater treatment have low surface tension and are insoluble in foaming media. Adding them to electroplating wastewater will not affect chemical substances such as biological bacteria in the water, and will not change the water quality and its basic system. In addition, high temperature resistance, acid and alkali resistance are also important characteristics. Electroplating wastewater contains alkali and other harsh environmental factors. Defoaming agents for electroplating wastewater treatment can quickly adapt to achieve rapid defoaming and long-term foam inhibition. Excellent water solubility can quickly dissolve with wastewater systems, achieving results.

    Congo Republic of the Congo Chemical foam in electroplating wastewater treatment is due to the existence of many surfactants such as detergent and colloidal organic matter in the wastewater, which have strong foaming ability. Therefore, under the conditions of water flow speed, fall, aeration, blowing off, etc., a large number of small and light white brown foam will appear on the surface of the wastewater, which is unstable. There are still some differences between biological foam and chemical foam in appearance, usually showing soil brown or grayish brown. There are many reasons for this kind of foam, such as the soil brown foam caused by the low dissolved gas in the biochemical tank. Grey brown foam produced by low MLSS. Foam caused by microbial factors such as microbial abnormalities. Filamentous bacteria grow abnormally, mix and accumulate with foaming and floc particles to form foam that is difficult to eliminate, etc. The defoamer for electroplating wastewater treatment uses modified silicon polyether and modified oxane as the main raw materials to eliminate foam. It can achieve good results for chemical foam and biological foam that may appear in the electroplating wastewater system.
