Wastewater Treatment Chemicals for Industrial and Municipal Applications

GN New Chem supplies specialty wastewater treatment chemicals for solid-liquid separation, sludge dewatering, oil and grease removal, color removal, foam control, odor control, and heavy-metal removal. Chemical programs can be optimized through laboratory testing and field trials to improve treatment efficiency, reduce sludge volume, and support stable plant operation.

Our portfolio is designed for clarification, flotation, biological-treatment support, sludge thickening and dewatering, oil and grease removal, color control, odor control and polishing before discharge or reuse. Rather than treating chemicals as isolated commodities, GN New Chem focuses on the complete operating objective: stable separation, predictable treatment performance, reduced process interruptions, manageable sludge or waste output, and practical chemical consumption.

Application-Focused Chemical Solutions

Treatment programs are selected according to the feed composition, process equipment, operating temperature, water chemistry, contamination profile and required outlet quality. The category serves municipal wastewater utilities, industrial plants, EPC contractors, environmental service companies, equipment integrators and chemical distributors. Products can be supplied as individual additives or as part of an integrated chemical program supported by laboratory screening, compatibility checks and field optimization.

Products in This Category

• Flocculants: High-performance anionic, cationic, and nonionic flocculants help aggregate fine suspended particles into larger, stronger flocs. They improve clarification, flotation, filtration, and centrifuge or belt-press dewatering performance in industrial and municipal wastewater treatment.
• Coagulants: Inorganic and organic coagulants destabilize colloids and fine suspended solids, enabling rapid floc formation and more efficient settling or dissolved-air flotation. Programs can be tailored for turbidity, color, oil, phosphorus, and heavy-metal removal.
• Sludge Dewatering Chemicals: Specialty sludge conditioning and dewatering chemicals improve floc strength, cake solids, centrate clarity, and equipment throughput. Formulations are selected according to sludge source, solids concentration, pH, salinity, and the selected dewatering equipment.
• Oil-Water Separation Chemicals: Oil-water separation chemicals help destabilize emulsified oil, aggregate dispersed droplets, and improve oil removal through gravity separation, flotation, filtration, or centrifugation. Solutions are suitable for refinery, petrochemical, metalworking, and oilfield wastewater.
• Defoamers and Antifoams: Wastewater defoamers and antifoams rapidly knock down existing foam and suppress foam generation in aeration tanks, biological treatment, chemical reaction, sludge handling, and industrial effluent systems, helping stabilize operations and prevent carryover.
• Odor Control Chemicals: Odor control chemicals help reduce hydrogen sulfide, mercaptans, ammonia, and other nuisance odors in wastewater collection, treatment, sludge storage, and dewatering operations. Programs can be designed for oxidation, neutralization, scavenging, or biological odor suppression.
• Decolorizing Agent: Decolorizing Agent remove dissolved or colloidal color through charge neutralization, adsorption bridging, and coagulation-flocculation. They can also reduce turbidity and part of the COD load. Applications include textile dyeing, paper, coking, ink, pigment, leather, and chemical wastewater. Jar testing should determine the chemical combination and dosage according to dye type, pH, salinity, and downstream treatment.
• Heavy Metal Removal Chemicals: Heavy metal removal chemicals precipitate, bind, or capture dissolved metals such as copper, nickel, zinc, lead, chromium, cadmium, and mercury. They are used to improve compliance in plating, mining, electronics, and chemical-industry wastewater.

Information Required for Product Recommendation

For a technically meaningful recommendation, please provide representative samples where possible, current treatment chemicals and dosage, process flow, equipment type, operating temperature, pH and salinity, contaminant or solids analysis, target outlet specification, daily treatment volume, packaging preference and destination country. GN New Chem will review the information and recommend a practical evaluation plan.
