In various industries the production of water treatment foam is inevitable, and businessmen often choose water treatment defoamer to remove the foam, good defoamer variety, and choose to a suitable defoaming is not difficult, but you know they will be in which water treatment technology will be used to?
Water treatment defoamer in which water treatment technology used
Water treatment has biological water treatment, wastewater treatment, seawater desalination water treatment, etc., and the diversity of water treatment defoamer is developed for different water treatment foam causes, so different kinds of water treatment defoamer in the elimination of foam technology use also varies.
The principle of foam generation:
1. biological water treatment defoamer, which uses the water treatment technology will choose the traditional activated sludge method as well as the fixed membrane method. Although their water treatment process is different, the principles of purification are not very different, mainly the solids in the sewage, floating materials, and other pollutants for precipitation, decomposition, filtration, and completion of water treatment, in this treatment process will produce a large number of non-metallic elements of nitrogen or in the flow of the impact of a large number of bubbles to affect the efficiency of water treatment, when the appropriate amount of added water treatment antifoam agent is very important.
2. Wastewater water treatment defoamer is the use of a mechanical treatment method and biochemical method of wastewater purification, mechanical treatment method is mainly the use of physical action to remove solids or oil floating in the water, and the water contains water-soluble polymers, easy to produce foam; and biochemical method is the organic matter or toxic substances in the wastewater through the chemical nature or physical state of the transformation and then filtering, during the reaction transformation will Generate a lot of foam, so also need to use water treatment defoamer to defoam.
3. Desalination of seawater is a rich technology, such as a chemical conditioning method, and desalination requires a variety of chemical substances, including input (NaPO3)6 to prevent the precipitation of calcium carbonate, and the OP(OR)₃ produced in this process will cause a large number of anaerobic organisms to reproduce, and they are prone to cause foam in the water, so the use of water treatment antifoam agent is also essential.
