Why use the seawater desalination treatment defoamer?
Water is the source of life, and now mankind's demand for water is increasing. Then comes the problem of shortage of fresh water resources. Seawater desalination treatment refers to a method of increasing the utilization rate of water resources by sending it to various production platforms after step-by-step filtration and deoxygenation treatment through a coarse filter, a fine filter, a deoxygenation tower. But in the process of seawater desalination, the problem of foam will be encountered, and foam is a big problem in seawater treatment engineering. At this time, it is necessary to add seawater desalination antifoam to solve the foam problem!
Seawater desalination antifoam is a special defoamer developed in combination with water treatment defoamer. It is a polysiloxane defoamer synthesized by a special process. The defoamer has strong foam breaking and defoaming effects, and the defoaming is rapid. Defoamer is not only suitable for defoaming at room temperature, but also for defoaming in high temperature and low temperature environments. Moreover, the antifoam is non-toxic and tasteless, and will not cause any pollution to the environment. When the water-based water treatment defoamer is used for defoaming, the dosage is small and the use cost is low.
Causes of Seawater Treatment Foam:
1. Eutrophication of seawater: Seawater contains a large amount of organic pollutants, nitrogenous substances and other components that lead to the generation of foam;
2. There are many algae plants in seawater, which contain a lot of protein, which can easily lead to the production of foam;
3. In the process of seawater treatment, the high-speed stirring of machinery and equipment will cause part of the air to be mixed, resulting in the generation of foam;
4. Seawater treatment will cause some microorganisms and algae to decompose rapidly, producing a large amount of organic matter and ammonia gas, resulting in the production of foam.
Hazards of Seawater Treatment Foams:
1. There is too much foam in seawater treatment, which will affect the development of offshore fisheries after treatment and discharge, resulting in reduced fishery production capacity and affecting fishermen's income;
2. Too much foam and not cleaned up in time. The discharge of some sewage containing foam will cause the seawater to be polluted, and some microorganisms and bacteria will multiply, resulting in a red tide crisis;
3. Too much foam will slow down the process, reduce production efficiency, and lead to an unnecessary increase in production costs.
The function and characteristics of seawater desalination defoamer:
1. The defoamer has fast defoaming speed and long foam suppression time. Adding water treatment defoamer to seawater can quickly defoam, and no foam will appear again in subsequent treatment and discharge;
2. The chemical stability of the antifoaming agent. Adding defoamer to seawater will not affect the pH of seawater, nor will it change the color and appearance of seawater;
3. The defoamer has good water solubility and dispersibility. The seawater desalination antifoam can be quickly dispersed into the seawater without precipitation and has good stability.
