How to choose wastewater defoamer in water treatment

Aug 30, 2024

With the development of China's industry, industrial wastewater emissions are increasing, for the complexity of the composition, the nature of many industrial wastewater, now commonly used wastewater treatment technology can be divided into multi-biochemical method, physical-chemical method, natural treatment method. No matter which technology is taken, in the process of industrial water treatment will often appear foam accumulation phenomenon, directly affecting the efficiency and quality of industrial production. For this reason, we need to add a certain amount of industrial water treatment defoamer in a timely manner, in order to quickly eliminate foam, lasting foam suppression.

Water treatment defoamer is a chemical substance used to control and reduce foam in the process of water treatment, the main component is a surfactant, with a certain degree of hydrophilicity and hydrophobicity. Its main role is to control and reduce the generation and diffusion of foam, improve the effect and quality of water treatment. In the water treatment industry, water treatment defoamer plays a vital role, providing a strong guarantee for water treatment and utilization.

For special industries and foaming system defoamer selection：

Coal chemical industry (high carbon alcohol emulsion defoamer).
Waste treatment plant leachate (high efficient silicone emulsion defoamer).
Power plant desulfurization (low price and high content of silicone defoamer and polyether defoamer).
Biological aeration tanks (non-silicone high-carbon alcohol defoamer, environmentally friendly and sustainable foam suppression).

Foam layer containing a large number of suspended matters in the system (mineral oil products, focus on instantaneous high-speed foam breaking).

Osmotic membrane treatment: non-silicon products, no destructive effect on the treatment membrane, very easy to disperse in water, can be very compatible with liquid products, do not break the emulsion bleaching oil.
Solid antifoaming powder for water treatment: solves the defects of general antifoaming agent emulsion in high electrolyte, strong acid, strong alkali, high shear system, which is easy to emulsify and fail.
