Talking about the Application and Selection of Water Treatment Defoamer

In sewage treatment, the foam prone environment is mainly the biological aeration tank and the sewage outlet. Sewage contains a lot of surface activity, because of the bubbling of gas in the biological aeration tank produces foam. The defoamers used in biological aeration tank should not affect the activity of bacteria in activated sludge, and should use non-silicon or less silicon defoamers as far as possible. The foaming of the outlet is caused by the impact of the water flow, which is relatively easy to eliminate. The requirement of the product is mainly concerned with the best choice of defoaming, and the high efficiency silicone product has fast foam breaking speed and better foam control effect. Our own R & D, production and sale of silicone (silicone and silicone polyether emulsion), non silicon defoamer (mineral oil, high carbon alcohol, polyether products) and solid defoamer (powder defoamer) adopt environment-friendly surfactant, no toxicity, no two pollution, to meet the needs of our customers to optimize the production site and environmental protection, and at the same time, professional bubbles. The system carries out targeted selection to ensure cost controllability and accuracy.

Traditional municipal wastewater treatment

The water treatment processes of iron and steel, mining, smelting, medicine, textile, pesticide fertilizer, electronics, textile leather, paper making, food and beverage, electroplating, artificial stone, circulating cooling water and other industries all have different degrees of foaming system: the foaming system of wastewater in this industry has different requirements for acid-alkali resistance and dispersion of defoamers due to its different acidity, viscosity and temperature. Clearly, the instantaneous bursting and sustained anti-foaming ability of the product are the primary concerns at present, (organic silicon and non-silicon defoamers with high acid and alkali resistance).

For special industries and bubble systems

Coal chemical industry (high carbon alcohol emulsion defoamer).

Landfill leachate (high efficiency silicone emulsion defoamer).

Power plant desulfurization (low-cost high-content silicone defoamer and polyether defoamer).

Biological aeration tank (non-silicon high-carbon alcohol defoamer, environmentally friendly and sustainable foam suppression).

The foam layer contains a large number of suspended solids (mineral oil products, focusing on instant high speed bubble breaking).

Permeation membrane treatment: non-silicon products, no damage to the treatment membrane, easy to disperse in water, can be well compatible with liquid products, non-demulsifying bleaching oil.

Water treatment solid defoaming powder: solves the general common defoamer emulsion in the high electrolyte, strong acid, strong alkali, high shear system easy to demulsification failure.
