The demulsifier for hardware wastewater is a high-efficiency chemical formulation specifically developed for wastewater generated from hardware manufacturing processes. It features the following advantages:
Rapid demulsification: Quickly breaks the emulsion between oil droplets and water in the wastewater, enabling fast phase separation.
Strong adaptability: Effectively treats hardware wastewater containing various types of oils, heavy metals, and additives.
Excellent removal performance: Achieves efficient oil-water separation while significantly reducing pollutants such as COD and heavy metals.
High stability: Maintains consistent demulsification performance across a wide range of temperatures and pH conditions.
Cost-effective and environmentally friendly: Requires low dosage, reduces treatment costs, and generates no secondary pollution, supporting compliant discharge of hardware wastewater.
Product Introduction：
Metalworking wastewater demulsifiers are chemical agents used to treat wastewater generated during metalworking processes. Metalworking wastewater comes from a wide range of sources, including grinding and cleaning, ultrasonic cleaning, emulsion wastewater, and cutting fluid replacement tank cleaning. Its composition is complex, containing large amounts of heavy metal ions (such as chromium, cadmium, nickel, copper, zinc, etc.), organic pollutants (such as grease, emulsions, surfactants, etc.), and may also contain suspended solids, hexavalent chromium, trivalent chromium, cyanide, etc.
These demulsifiers primarily leverage their unique chemical properties to break emulsions and induce flocculation of emulsified oils, colloids, and other substances in wastewater, thereby achieving oil-water separation and pollutant removal.
Some demulsifiers integrate the characteristics of multiple electrolytes, polymeric flocculants, and wetting agents. They reduce the interfacial tension of oil-in-water emulsions, neutralize the negative charges on the surface of the liquid film, and promote rapid coalescence and separation of emulsified oil from water.
Other demulsifiers contain surfactants that interact with oily contaminants in the wastewater, disrupting their emulsified state. Alternatively, they may employ precipitating agents that react with suspended solids to form easily settleable complexes, facilitating the sedimentation and separation of both oil and solid particulates.
Product Advantages：
Excellent demulsification and removal performance: Rapidly and effectively breaks emulsions to achieve efficient oil-water separation, demonstrating high removal efficiency for contaminants commonly found in hardware wastewater—such as oils, heavy metal ions, and suspended solids—resulting in significantly improved effluent quality.
Cost-saving: Integrating multiple functions—including demulsification, flocculation, and sedimentation—into a single formulation, it effectively aggregates and precipitates impurities from water. This significantly simplifies the treatment process, reduces the number of required treatment steps, and lowers both capital investment and operational costs.
Strong adaptability: Available in both liquid and solid forms, with liquid products suitable for direct dosing or after dilution. It is effective over a wide pH range; for example, certain formulations perform optimally in wastewater with a pH between 5 and 12, achieving the best demulsification and coagulation results around pH 9.
