On the role of desulfurization wastewater treatment defoamer
Sep 13, 2024
In the production process of gypsum, we can often find that in order to maintain the balance of the circulatory system of the desulfurization plant, often need to remove a certain amount of wastewater, and this wastewater often contains a lot of heavy metals and harmful suspended solids, therefore, in order to ensure that the subsequent water treatment can be a good operation, the subsequent water treatment manufacturers will also be put into the appropriate amount ofdesulfurization wastewater treatment defoamer in order to reduce the water source foaming and subsequent foam suppression has made an outstanding contribution.
We all know that the desulfurization wastewater formed by the construction steps, after a variety of filtration and processing, the concentration of wastewater from the reaction pool slowly out of the wastewater, which not only takes away the excess suspended solids, there are a large number of saturated sulfites, which has caused a major difficulty in water treatment, so this wastewater often needs to be recycled many times in order to meet the discharge standards. However, with the recycling of wastewater filtration, a large number of microorganisms and foam groups will grow from it, problems will arise, such as clogging of filters, chemicals can not be directly to the water source, wastewater treatment time is longer and so on.
The role of defoamer is to separate the gas from the liquid film from thick to thin until the process of rupture. To add antifoaming agent to the foaming liquid, antifoaming agent particles quickly dispersed in the bubbles on the surface of the liquid film, and then gradually to the liquid film surface expansion, so that the liquid film is getting thinner and thinner and ultimately rupture. Antifoam agent in water can also adsorb microorganisms to reduce the volatilization, reduce the formation of foam factors, to achieve the efficacy of long-term foam suppression.
