Product Introduction：

Demulsifier for surfactant-containing wastewater is a chemical agent specifically used to treat wastewater containing surfactants. Such wastewater typically forms highly stable emulsions, making treatment challenging. The ionic components in the demulsifier neutralize the surface charges of the emulsion droplets, promoting their approach and coalescence. Additionally, through the mechanism of electrical double-layer compression, the demulsifier reduces both the thickness and stability of the double layer surrounding the emulsion droplets, thereby achieving effective demulsification.

There are various common types of demulsifiers for wastewater containing surfactants, including inorganic salt-based demulsifiers (such as aluminum sulfate, ferric chloride, etc.). These demulsifiers generate positively charged polynuclear complexes through hydrolysis, which then undergo charge neutralization and adsorption bridging with negatively charged emulsified droplets. There are also surfactant-based demulsifiers that, relying on their special molecular structures, competitively adsorb at the oil-water interface with the original emulsifiers, altering the interfacial properties. Additionally, there are high-molecular-polymer-based demulsifiers (such as polyacrylamide, etc.) that utilize the adsorption bridging effect of their long-chain molecules to connect multiple emulsified droplets, forming large aggregates and accelerating oil-water separation.

Product Advantages：

High-Efficiency Demulsification: Effectively breaks the emulsified systems in surfactant-containing wastewater, achieving initial oil-water separation and creating favorable conditions for subsequent advanced treatment processes (such as biological treatment or chemical oxidation).

Cost Reduction: Significantly improves wastewater treatment efficiency, thereby lowering overall treatment costs.

Removal of Multiple Pollutants: During the demulsification process, it effectively removes color, chemical oxygen demand (COD), biochemical oxygen demand (BOD), suspended solids (SS), surfactants, and other organic contaminants from the wastewater.

Environmentally Friendly: It poses no harm or adverse effects to downstream biological treatment systems; in fact, it can even reduce the cost of subsequent biological processes, thereby addressing environmental concerns at their root. The treated effluent exhibits excellent water quality and does not re-turbidify over time.

Flexible Operation: It can be used without dedicated equipment or integrated into various treatment systems to accelerate demulsification and decolorization, and is also compatible with dissolved air flotation (DAF), biological treatment, and other equipment.

Service Industries：

Fine Chemical Industry: The production processes in the fine chemical industry are complex, and the resulting wastewater often contains high concentrations of organic solvents, surfactants, and various additives. Demulsifiers can effectively treat such wastewater.

Petrochemical Industry: It can be used to treat wastewater containing surfactants generated during petroleum extraction, oil refining, storage and transportation at oil depots, petrochemical production, and chemical manufacturing. It effectively removes emulsified oils and solid particles, ensuring that the treated effluent meets discharge standards.

Electronics Manufacturing Industry: Suitable for treating surfactant-containing wastewater generated from various electronic manufacturing processes, such as cleaning, etching, and coating operations.

Hardware and Mechanical Processing Industries: Wastewater from hardware manufacturing and mechanical processing typically contains high levels of COD, suspended solids (SS), and surfactants, which can be effectively treated using demulsifiers.
