Water treatment defoamer teaches you to defoam
Every day, both domestic and industrial production produce a large amount of wastewater, which usually requires certain treatment before it can be discharged and needs to meet discharge standards before it can be discharged. The water treatment methods include physical and chemical treatment. The treatment process often produces large amounts of foam, which is caused by the spread of bacterial growth in the wastewater. These foams will affect the progress of water treatment if not treated in time, it is best to use water treatment defoamer to defoam.
Water treatment defoamer has the following 4 defoaming principles in wastewater foam.
1. liquid film drainage effect, after the formation of foam, the outside will form a liquid film. The addition of water treatment defoamer can promote the drainage of liquid film, destabilize the foam, so as to eliminate the foam.
2. reduce the tension, the long existence of foam, can not be separated from the surface tension of the foam. Water treatment defoamer can reduce the tension of the foam surface, so that the foam can not be stable, so as to eliminate the foam.
3. Destroy the elasticity of the foam surface film. Surface active substances are very easy to cause foam, defoamer can destroy the elasticity of the foam surface film, so that it can not be formed, lose elasticity, so that the natural foam lost the basis of existence.
4. reduce the concentration of surfactants, water treatment defoamer can effectively reduce the concentration of surfactants, dissolve the adsorption layer of surfactants, and destroy the conditions of foam formation.
Water treatment defoamer fast defoaming speed, long-lasting foam inhibition, used in pharmaceutical, paper, leather, oilfield, power plant desulfurization, lubricants, cleaning agents and municipal sewage biological treatment process and other foaming system.
The efficacy performance of wastewater treatment defoamer is.
1. Sewage treatment defoamer has low surface tension, high activity and strong defoaming power.
2. Defoamer heat-resistant high temperature no change, low volatility.
3. Wastewater treatment defoamer chemical stability, chemical inertness, does not reflect with other substances, can be used in harsh conditions.
4. Defoamer both defoaming, foam inhibition, foam inhibition time up to 48 hours or more.
