Elimination of foam
(1) Physical methods
From the physical point of view, the methods to eliminate foam mainly include placing baffle or filter screen, mechanical agitation, static electricity, freezing, heating, steam, radiation, high-speed centrifugation, pressure reduction, high-frequency vibration, instantaneous discharge and ultrasound (acoustic liquid control). These methods promote the gas transmission rate at both ends of the liquid film and the liquid discharge of the bubble film to varying degrees, making the stability factor of foam less than the attenuation factor, As a result, the number of foam gradually decreased. However, the common disadvantage of these methods is that their use is strongly restricted by environmental factors, and the defoaming rate is not high. The advantages are environmental protection and high reuse rate.
Somalia The antifoaming agent for aquaculture wastewater treatment is paint defoamerfor the aquaculture wastewater industry system. It can quickly disperse in water, is easily soluble in water, is not easy to break emulsion and float oil, and is fast in paint defoamer and long in inhibiting foam. It does not change the oxygen content of water quality or the microorganisms in the water, and has good acid and alkaline resistance, wide application range, and good chemical stability.
