Zetag 8127 DL is a high-performance cationic polyacrylamide (CPAM) dry powder flocculant developed for efficient solid–liquid separation, sludge dewatering, and wastewater clarification. It is characterized by high molecular weight, medium-to-high cationic charge density, rapid flocculation speed, strong floc structure, and excellent water-release performance. Because most suspended solids, biological sludge, and organic colloids in wastewater systems are negatively charged, Zetag 8127 DL is particularly effective through charge neutralization and polymer bridging, which form dense, shear-resistant flocs. Its main applications cover municipal wastewater, industrial effluent, papermaking, oil and gas, food processing, and mining sludge treatment.

1. Municipal Sludge Dewatering

The primary and most important application of Zetag 8127 DL is in municipal wastewater treatment plants (WWTPs) for sludge conditioning and dewatering. It is widely used in:

• Belt filter presses

• Decanter centrifuges

• Screw press dehydrators

• Plate and frame filter presses

Zetag 8127 DL performs exceptionally well on activated sludge, digested sludge, and mixed primary–secondary sludge. By neutralizing surface charges and bridging particles into large flocs, it significantly improves cake dryness, reduces filtrate turbidity, and lowers overall sludge volume. As a result, transportation costs, landfill volume, and post-treatment energy consumption are reduced. The polymer’s strong floc structure also minimizes sludge breakage during high-shear dewatering processes such as centrifugation.

2. Industrial Sludge Dewatering

Zetag 8127 DL is extensively used in industrial wastewater treatment plants where sludge contains high levels of organic matter, fine particles, oils, or chemical residues. Typical sectors include:

• Textile and dyeing factories

• Chemical and pharmaceutical plants

• Electroplating and metal finishing facilities

• Printing ink and pigment manufacturing

• Rubber, resin, and plastics production

In these industries, sludge is often sticky, compressible, and difficult to separate using mechanical methods alone. Zetag 8127 DL rapidly forms compact flocs that improve dewatering speed, filter press efficiency, and solid capture rate, even at low dosage. It also helps stabilize variable wastewater quality and enhances treatment plant operational reliability.

3. Wastewater Clarification and Suspended Solid Removal

Beyond sludge dewatering, Zetag 8127 DL is widely applied as a primary flocculant or coagulant aid in wastewater clarification processes. It is particularly effective for effluents dominated by organic suspended solids, such as:

• Papermaking white water

• Food and beverage wastewater

• Slaughterhouse and rendering plant wastewater

• Fermentation and alcohol production wastewater

• Pharmaceutical and fine chemical effluent

In clarification tanks, dissolved air flotation (DAF) units, and lamella settlers, Zetag 8127 DL accelerates particle aggregation and settling, producing a clear supernatant with low residual turbidity. It also improves the separation of fats, proteins, fibers, and suspended carbonaceous materials, contributing to lower COD and TSS in final effluent.

4. Papermaking Industry Applications

In the pulp and paper industry, Zetag 8127 DL plays multiple roles:

• Sludge dewatering agent for primary and biological paper mill sludge

• White water clarification flocculant

• Retention and drainage aid at the wet end

Paper mill wastewater contains large quantities of cellulose fibers, fillers, kaolin, calcium carbonate, and residual chemicals. Zetag 8127 DL effectively captures these fine solids, improving sludge dewatering efficiency while reducing fiber loss. As a retention aid, it enhances filler and fine fiber retention on the wire, improves drainage speed, stabilizes papersheet formation, and helps increase machine productivity.

5. Oilfield, Refinery, and Petrochemical Wastewater

In the oil and gas industry, Zetag 8127 DL is widely used for:

• Oilfield produced water clarification

• Refinery wastewater treatment

• Oily sludge thickening and dewatering

Oilfield and refinery wastewater typically contains emulsified oil, drilling solids, polymer residues, and organic sludge. Zetag 8127 DL promotes efficient aggregation of oil–solid mixtures, enhances oil–water separation, and improves the performance of flotation, sedimentation, and mechanical dewatering systems. It also contributes to reduced chemical oxygen demand (COD) and compliance with environmental discharge standards.

6. Food Processing and Beverage Industry

Zetag 8127 DL is highly effective in food and beverage wastewater treatment, where effluent contains large amounts of starch, protein, fats, sugar, yeast, and suspended biomass. It is commonly used in:

• Slaughterhouses and meat processing plants

• Dairy factories

• Breweries and distilleries

• Sugar, starch, and starch-derivative plants

The polymer rapidly forms dense flocs with organic solids, improving DAF performance, clarifier efficiency, and sludge dewatering results. This leads to clearer effluent, reduced biological load on downstream treatment units, and lower sludge disposal cost.

7. Mining, Metallurgy, and Mineral Processing

In mining and metallurgical operations, Zetag 8127 DL is used mainly for:

• Sludge dewatering in tailings and sludge treatment systems

• Clarification of mineral processing wastewater

• Thickener underflow conditioning

Refining and mineral processing generate large volumes of fine suspended solids and metallic hydroxide sludge. Zetag 8127 DL improves sedimentation rate, enhances filter press throughput, and supports efficient water recycling in closed-loop systems.

Conclusion

Zetag 8127 DL is a versatile, high-efficiency cationic flocculant primarily designed for sludge dewatering and organic-rich wastewater treatment. Its strong charge neutralization ability, rapid floc formation, and excellent water-release characteristics make it indispensable in municipal wastewater plants, industrial effluent treatment, papermaking, oilfield and refinery wastewater, food processing, and mining sludge systems. By significantly improving dewatering performance, reducing sludge volume, and enhancing effluent clarity, Zetag 8127 DL plays a key role in lowering operating costs, improving environmental compliance, and ensuring stable plant operation.
