Defoaming agents should have the following properties: ① strong defoaming power and low dosage; ② Adding to the foaming system does not affect the basic properties of the system, i.e. does not react with the defoaming system; ③ Low surface tension; ④ Good balance with the surface; ⑤ Good heat resistance; ⑥ Good diffusion and permeability, high positive spreading coefficient; ⑦ Chemical stability, strong oxidation resistance; ⑧ Good gas solubility and permeability; ⑨ Low solubility in foaming solutions; ⑩ No physiological activity, high safety.

Turkmenistan The antifoaming agent for aquaculture wastewater treatment is ink 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 ink 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.
