Application of ZETAG 8167

ZETAG 8167 is a high-performance cationic polyacrylamide (CPAM) flocculant widely used in municipal wastewater treatment, industrial effluent clarification, sludge dewatering, sludge thickening, and selected mineral-related water treatment applications. It is engineered with high molecular weight and moderate cationic charge density, allowing it to efficiently neutralize negatively charged particles and create strong, shear-resistant flocs. Due to its reliable performance under varying operating conditions, ZETAG 8167 is commonly selected for demanding solid–liquid separation processes.

1. Municipal Wastewater Treatment

The primary application of ZETAG 8167 is in municipal wastewater treatment plants, particularly in sludge conditioning and mechanical dewatering operations. Municipal sludge typically contains biological solids, microorganisms, colloidal organic matter, and fine particulates, all of which carry negative surface charges.

Key municipal applications include:

• Sludge dewatering: ZETAG 8167 is highly effective in centrifuges, belt filter presses, screw presses, and filter presses. It promotes the formation of compact, durable flocs that release free water rapidly.

• Improved cake dryness: Enhanced water removal leads to higher dry solids content in the dewatered sludge cake, reducing disposal and transportation costs.

• Stable operation: The polymer provides consistent flocculation even when sludge characteristics fluctuate due to seasonal or load variations.

Because of its fast floc formation and good shear resistance, ZETAG 8167 is especially suitable for high-speed dewatering equipment.

2. Industrial Wastewater Treatment

ZETAG 8167 is widely used in industrial wastewater treatment systems to remove suspended solids, organic contaminants, and fine colloidal particles.

Industries where ZETAG 8167 is commonly applied include:

• Food and beverage processing: Effectively flocculates organic solids, fats, oils, proteins, and starch residues, improving effluent clarity and reducing the load on biological treatment systems.

• Chemical and pharmaceutical manufacturing: Enhances clarification of complex waste streams containing fine particles and emulsified organic compounds.

• Textile and dyeing industries: Assists in removing fibers, dyes, and colloidal pigments, reducing turbidity and color.

• Metal finishing and electroplating: Improves separation of metal hydroxides and fine suspended solids following pH adjustment and precipitation.

In industrial applications, ZETAG 8167 works through a combination of charge neutralization and polymer bridging, producing large, fast-settling flocs that improve clarification efficiency.

3. Sludge Thickening Applications

Another important application of ZETAG 8167 is sludge thickening, where the objective is to increase solids concentration prior to dewatering or disposal.

Benefits in thickening systems include:

• Faster settling rates in gravity thickeners

• Higher underflow solids concentration

• Reduced hydraulic load on downstream dewatering equipment

• Improved overall plant capacity and stability

ZETAG 8167 performs well in thickening biological sludge, mixed sludge, and industrial slurries, particularly those with high organic content or fine particle size distributions.

4. Pulp and Paper Industry

In the pulp and paper industry, ZETAG 8167 is applied as a sludge dewatering agent and retention aid.

Typical applications include:

• Paper mill sludge dewatering: Improves dewatering efficiency of primary and secondary sludge, reducing sludge volume and disposal costs.

• Fiber and filler retention: Enhances retention of fines, fillers, and pigments during paper sheet formation.

• White water clarification: Improves clarity of process water, enabling internal water recycling and reduced fresh water consumption.

By improving retention and drainage, ZETAG 8167 contributes to improved machine efficiency and consistent paper quality.

5. Mining and Mineral-Related Water Treatment

Although ZETAG 8167 is not primarily designed for mineral beneficiation, it is frequently used in mine water treatment and mineral-related wastewater applications.

Applications include:

• Clarification of mine water: Removes fine suspended solids from process water, pit water, and tailings pond overflow.

• Sludge dewatering: Improves dewatering of mineral sludges generated during washing, flotation, or ore processing.

• Water recycling: Enables reuse of clarified water within mining operations, reducing fresh water demand.

The flocs formed by ZETAG 8167 exhibit good resistance to shear and moderate tolerance to salinity, making it suitable for challenging mining environments.

6. Environmental and Operational Advantages

The use of ZETAG 8167 offers several environmental and economic benefits:

• Reduced chemical consumption: High flocculation efficiency lowers overall polymer dosage.

• Improved water recovery: Supports recycling and reuse of treated water.

• Lower sludge disposal costs: Higher cake solids and reduced moisture content.

• Operational reliability: Stable performance across a wide range of sludge and wastewater conditions.

These advantages make ZETAG 8167 an attractive choice for facilities focused on cost control and sustainable operation.

7. Dosage and Handling Guidelines

• Typical dosage: 1–10 mg/L in wastewater treatment or 2–8 kg per ton of dry sludge solids, depending on sludge characteristics and equipment type.

• Preparation: Supplied as a dry powder, ZETAG 8167 must be properly dissolved and aged to ensure full polymer hydration and activation.

• Safety: Non-hazardous under normal industrial use; standard personal protective equipment such as gloves and eye protection is recommended.

Laboratory jar testing and on-site trials are essential to optimize dosing and achieve the best performance.

Conclusion

ZETAG 8167 is a versatile and efficient cationic polyacrylamide flocculant widely applied in municipal wastewater treatment, industrial effluent clarification, sludge thickening, sludge dewatering, pulp and paper processing, and mining-related water treatment. Its balanced combination of cationic charge density and high molecular weight ensures rapid flocculation, strong floc structure, and excellent dewatering performance. By improving solid–liquid separation, reducing sludge volume, and enhancing water recovery, ZETAG 8167 plays an important role in modern, efficient, and environmentally responsible water and sludge treatment systems.
