Water Treatment Chemicals Industrial Wastewater Defoaming Agent

(1 Overview

Many bubbles are generated in the process of industrial production. Bubbles and foams often accompany people's lives and production. Sometimes they need to be used, such as flotation, fire extinguishing, dust removal, washing, making foam ceramics and plastics, etc.; sometimes they need to be eliminated, such as fermentation, coatings, papermaking, printing and dyeing, boiler water, wastewater treatment and prism (or glass) manufacturing. The so-called "bubbles" or "bubbles" refer to insoluble gases existing in liquids or solids, or existing in independent bubbles surrounded by their thin films. The accumulation state of bubbles gathered together and separated by thin films is called foam. Bubbles are a dispersed system with gas/liquid, gas/solid, and gas/liquid/solid interfaces. The latter is commonly seen in bubbles in mineral processing and oil field systems. Generally speaking, water and surfactants have less foaming because their surfaces and interiors are uniform and it is difficult to form an elastic film. Even if they are formed, they are unstable and will disappear instantly. However, there is a surfactant in the solution. After the bubbles are formed, due to the action of intermolecular forces, the hydrophilic and hydrophobic groups in the molecules are adsorbed by the bubble wall to form a regular arrangement, with the hydrophilic groups facing the water phase and the hydrophobic groups facing the inside of the bubble, thus forming an elastic film on the bubble interface. It is very stable and not easy to break under normal conditions. The stability of the foam is related to factors such as surface viscosity and elasticity, electrical repulsion, movement of the surface film, temperature, and evaporation. The surface tension of bubbles is inversely related to that of the liquid. The smaller the tension, the easier it is to foam. In life and production, sometimes foam appears.

Industrial wastewater defoaming agent is a defoaming agent for various types of water treatment. The sewage silicone defoamer is made of organic silicone resin using various emulsifiers and using emulsification technology and equipment to emulsify into a water-emulsion-dispersible defoamer that can be used under different temperatures and acid-base conditions.

(2) Main features

①Water treatment agent foam.

② Diluted with water, it has good compatibility with the foaming medium.

③ Defoaming and anti-foaming properties, it can maintain good defoaming and anti-foaming effects at lower concentrations.

(3) Performance indicators

(4) Scope of use

Sewage silicone defoamer is widely used in various sewage and wastewater treatment, circulating water treatment, paper mill sewage treatment, dye plant sewage treatment, chemical plant sewage treatment, industrial wastewater treatment, printing and dyeing sewage, urban sewage biological treatment and chemical cleaning, etc.

(5) Usage

Add to the medium environment or dilute with appropriate amount of water before use. If it can be fully stirred and dispersed in the foaming, it can be added. The dosage depends on different foaming materials and is determined after trial. It is generally 0.05% to 0.2%. The amount added is determined by the actual trial of the customer.
