Wastewater treatment defoamer defoaming explanation
Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater, purify it, reduce pollution, recycle and reuse it, and make full use of water resources. Wastewater contains water from domestic and industrial use, which needs to be treated before it can be discharged, and this process will encounter the problem of foam, too many impurities in the water will lead to a large amount of foam. Too much foam will affect the progress of water treatment, it is recommended to use wastewater treatment defoamer to eliminate these foams.
The wastewater treatment defoamer contains active ingredients, emulsifiers, carriers and emulsification aids.
1. Active material: that is, the main defoamer for wastewater treatment antifoaming and foam inhibition substances, common silicone, polyether and mineral oil, etc.. General sewage treatment defoamer are silicone polyether compound defoamer, more specific and more for the needs of the water treatment industry.
2. Emulsifier: to help the active ingredients dispersed into small particles, easy to disperse in the water, play a good dispersion and compatibility, better play the role of defoaming and foam inhibition, plus the help of emulsification additives, so that the defoamer emulsification effect is better.
3. Carrier: help defoamer and foaming system combination, defoamer defoaming and foam inhibition at the same time to reduce costs.
Wastewater treatment defoamer defoaming principle and role：
In general, the defoamer diffuses in the foam, forms a film on the foam wall, and then discharges the surfactant with foaming properties, thus reducing the local surface tension of the foam and destroying the self-healing effect of the foam, which is the foam rupture.
The wastewater treatment defoamer has excellent defoaming and anti-foaming properties, and can be added after the foam is generated or added to the product as a foam inhibiting component, depending on the use of different systems, the amount of defoamer can be added from 10 to 1000 ppm, the exact amount added by the customer according to the specific test decision.
Wastewater treatment defoamer products can be used directly or after dilution. If it can be fully stirred and dispersed in the foaming system, it can be added directly without dilution. If dilution is needed, follow the attached dilution method. Directly dilute the product with water is not desirable, easy to appear layered emulsion breaking and other phenomena, thus affecting the quality of defoamer products.
