Attenuation mechanism of foam
Under the condition of gravity and pressure difference, the liquid membrane of foam will flow and discharge liquid unevenly, and the gas in the bubble will continue to diffuse and permeate due to the different pressure difference on both sides of the bubble membrane, so the instability of foam itself is mainly reflected from the dynamics. [4]
The attenuation mechanism mainly includes the diffusion of gas through the liquid film and the discharge of liquid from the liquid film. These two properties are inherent attributes of foam itself, and have nothing to do with the existence of surfactant. However, these two attenuation mechanisms only play an obvious role in the initial stage of foam system formation. With the attenuation of foam system, these two effects gradually weaken, making the foam attenuation rate gradually slow. [

Barbados When general sand washing plants are carrying out sewage treatment, they should start to add chemicals to assist after the completion of sediment separation, fine sand extraction and other work. However, the complex composition of such chemicals combined with the influence of external factors will produce foam in sand washing wastewater treatment, which will bring only disadvantages but no benefits. For the treatment of sediment and sand washing wastewater, the sand washing wastewater treatment defoamer can not be more appropriate to eliminate the foam problem. It is targeted at the foaming mechanism and link system of the sand washing system. The finished products are mainly refined from organosilicon, polyether and other core components. Directly adding at the water inlet will not affect the separation and cleaning of sediment and other sediment,
