Germany 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,

There is no unified understanding of the mechanism of defoaming agents. According to the mechanism of defoaming agents proposed by predecessors, there are generally the following types: [4]
General defoaming mechanism
Typical defoaming mechanisms with a broad overview are the Robinson defoaming mechanism and the Ross hypothesis. Among them, Robinson mechanism is the basis of Ross hypothesis, which mainly emphasizes the liquid drainage of defoamer destroying foam and Marangoni effect to realize defoaming; The Ross hypothesis is based on the fact that the defoamer particles are insoluble droplets, while some defoamers actually produce defoaming effects in a dissolved state, so the defoaming mechanism of the Ross hypothesis is not comprehensive

Germany In addition, the sand washing wastewater treatment Free of silicone defoamersr can also be used for the wastewater after sediment cleaning. This system is different from wastewater treatment. In order to make the sediment cleaning effect better, the staff will add stabilizer and cleaning agent to assist in cleaning. The foaming factor in these additives is also one of the culprits for the emergence of a large number of foam. The polyethers in the sand washing wastewater treatment Free of silicone defoamers are specially designed for the sediment cleaning system, mainly to solve the foam in the process of water circulation washing sediment, and also applicable to the water treatment stage in the mud water separation.
