ZETAG 8127 DL is a high-performance cationic polyacrylamide (CPAM) supplied in liquid emulsion form, specifically developed for efficient solid–liquid separation, sludge dewatering, and wastewater clarification. It features medium-to-high cationic charge density combined with high molecular weight, allowing it to deliver strong charge neutralization and polymer bridging effects. Due to its fast dissolution, low dosage requirement, and excellent adaptability to different sludge and wastewater types, ZETAG 8127 DL is widely used in municipal treatment plants and a broad range of industrial sectors.

1. Municipal Wastewater Treatment

One of the most important applications of ZETAG 8127 DL is in municipal sewage treatment systems. Domestic wastewater contains a high concentration of negatively charged colloidal particles, organic matter, microorganisms, and fine suspended solids that do not settle easily without chemical assistance. ZETAG 8127 DL effectively neutralizes the surface charges of these particles and forms large, compact flocs through polymer bridging.

In primary and secondary clarification, the product significantly improves:

• Sedimentation speed

• Clarifier throughput

• Effluent turbidity reduction

• Total suspended solids (TSS) removal

In sludge conditioning, ZETAG 8127 DL is dosed ahead of belt filter presses, centrifuges, screw presses, and plate-and-frame presses. The polymer enhances floc strength and water release, resulting in:

• Higher dry solids content in sludge cake

• Lower sludge volume for transport and disposal

• Reduced energy consumption in dewatering operations

2. Industrial Wastewater Treatment

ZETAG 8127 DL is widely applied in textile, dyeing, chemical, pharmaceutical, food processing, electroplating, leather, and metallurgy industries, where wastewater typically contains complex mixtures of suspended solids, dyes, oils, and heavy metals.

Textile and Dyeing Industry

Textile wastewater contains reactive dyes, pigments, surfactants, and short fibers that are difficult to remove using gravity settling alone. ZETAG 8127 DL strongly binds with anionic dyes and fiber fines, delivering rapid flocculation and excellent color removal. Treated water shows reduced turbidity and improved transparency, making it suitable for further biological treatment or partial reuse.

Electroplating and Metal Processing

Electroplating effluents contain heavy metals such as nickel, chromium, zinc, and copper. After chemical precipitation, ZETAG 8127 DL aids in the aggregation of fine metal hydroxide particles. This improves sedimentation and filtration efficiency, reducing residual metal content in discharge water and ensuring compliance with environmental regulations.

Chemical and Pharmaceutical Effluents

Fine organic solids, polymer residues, and micro-colloids are common in chemical and pharmaceutical wastewater. ZETAG 8127 DL improves solid–liquid separation, lowers the load on biological treatment systems, and stabilizes overall plant operation.

3. Sludge Dewatering and Conditioning

Sludge dewatering is a core application area for ZETAG 8127 DL. Sludge from municipal and industrial processes contains a large amount of bound water held by negatively charged organic materials. This bound water limits dewatering efficiency unless properly conditioned.

ZETAG 8127 DL works by:

• Neutralizing sludge surface charges

• Breaking the hydration layer around particles

• Forming dense, shear-resistant flocs

As a result, it delivers:

• Faster filtration rates

• Higher cake dryness

• Lower polymer consumption per ton of dry solids

• Improved capacity of dewatering equipment

It performs reliably across different sludge types, including:

• Activated sludge

• Biological sludge

• Mixed industrial sludge

• Oily sludge

4. Papermaking and Pulp Industry

In the papermaking industry, ZETAG 8127 DL is primarily used as:

• A retention aid

• A drainage aid

• A sludge dewatering agent

During paper formation, fine fibers and fillers such as calcium carbonate and clay tend to escape with white water. ZETAG 8127 DL improves first-pass retention, enhances drainage on the wire section, and contributes to improved paper strength, surface quality, and formation uniformity. Improved retention also leads to lower raw material losses and reduced pollution load in papermaking wastewater.

For paper mill sludge treatment, ZETAG 8127 DL increases dewatering efficiency, reduces energy demand for thermal drying, and lowers the cost of sludge disposal.

5. Food and Beverage Industry

Wastewater generated from brewery, dairy, sugar, starch, beverage, and slaughterhouse operations typically contains proteins, fats, carbohydrates, and suspended organic solids. ZETAG 8127 DL is highly effective in clarifying these effluents by rapidly separating suspended solids and grease.

In dissolved air flotation (DAF) systems, it is often used together with inorganic coagulants such as PAC or aluminum sulfate to enhance bubble-particle attachment, improve flotation efficiency, and produce clearer effluent.

6. Mining and Mineral Processing

ZETAG 8127 DL is also applied in:

• Tailings thickening

• Mineral slurry dewatering

• Process water clarification

Fine mineral particles carry strong negative charges and remain suspended for long periods without chemical assistance. ZETAG 8127 DL promotes rapid aggregation and settlement, producing:

• High-density underflow

• Clear overflow water for recycling

• Improved tailings management and water reuse

This reduces freshwater consumption and enhances environmental protection at mining sites.

7. Oilfield and Drilling Wastewater

In oil and gas operations, ZETAG 8127 DL is used to treat:

• Produced water

• Drilling mud wastewater

• Refinery wastewater

It effectively removes fine suspended solids, clay particles, and emulsified oil droplets, ensuring the treated water meets reuse or discharge standards.

8. Advantages of ZETAG 8127 DL

Key advantages include:

• High flocculation efficiency at low dosage

• Fast dissolution and easy handling

• Strong floc structure and rapid settling

• Excellent sludge dewatering performance

• Wide adaptability to different pH and temperature conditions

• Strong compatibility with inorganic coagulants

Conclusion

ZETAG 8127 DL is a highly efficient cationic polyacrylamide emulsion flocculant with proven performance in municipal wastewater treatment, industrial effluent clarification, sludge dewatering, papermaking, food processing, mining, and oilfield water treatment. Its strong charge neutralization ability, high molecular weight, and excellent floc strength enable it to significantly improve solid–liquid separation efficiency, reduce operating costs, and support sustainable water and sludge management. As environmental regulations continue to tighten worldwide, ZETAG 8127 DL remains a reliable and cost-effective solution for modern wastewater and sludge treatment systems.
