Application of Cationic Polyacrylamide AGEFLOC 1071-AP

AGEFLOC 1071-AP is a high-performance cationic polyacrylamide (CPAM) widely used in wastewater treatment, sludge dewatering, papermaking, and industrial effluent clarification. With its high molecular weight and medium-to-high cationic charge density, it provides excellent charge neutralization and polymer bridging, enabling efficient aggregation of negatively charged particles such as suspended solids, organic matter, fibers, and colloids. The “AP” designation refers to a powdered or water-dispersible form, which ensures ease of storage, handling, and controlled dissolution in water systems.

AGEFLOC 1071-AP is specifically designed for applications where high flocculation efficiency, strong sludge dewatering, and rapid solid–liquid separation are required. Its unique combination of molecular weight and cationic charge makes it particularly effective in systems where organic solids dominate, including municipal wastewater, industrial effluent, and pulp and paper processing.

1. Municipal Wastewater Treatment

One of the most significant applications of AGEFLOC 1071-AP is in municipal wastewater treatment plants. Municipal sewage contains suspended solids, organic colloids, bacteria, and other negatively charged particles that cannot settle effectively on their own. AGEFLOC 1071-AP acts as a primary flocculant or coagulant aid, improving sedimentation in both primary and secondary clarification processes.

• In primary clarification, the polymer rapidly forms dense, settleable flocs by neutralizing surface charges and bridging particles, reducing total suspended solids (TSS) and part of the chemical oxygen demand (COD) prior to biological treatment.

• In secondary clarification, AGEFLOC 1071-AP improves sludge settleability and floc integrity, reducing issues like sludge bulking and floating that can occur in activated sludge systems.

• When used for sludge thickening and dewatering, AGEFLOC 1071-AP enhances performance on belt filter presses, centrifuges, and plate-and-frame filter presses, resulting in higher sludge cake dryness, reduced filtrate turbidity, and lower polymer dosage.

By improving the overall efficiency of municipal treatment processes, AGEFLOC 1071-AP helps plants reduce chemical costs, lower sludge disposal volume, and maintain compliance with stringent effluent discharge standards.

2. Industrial Wastewater Treatment

AGEFLOC 1071-AP is widely applied in industrial wastewater treatment, particularly where effluent contains high concentrations of organic solids, oils, greases, and fine suspended particles. Industries that commonly use this polymer include:

• Food and beverage processing

• Meat, poultry, and seafood operations

• Textile and dyeing plants

• Chemical and pharmaceutical manufacturing

• Leather tanning

• Pulp and paper mills

• Electroplating and metal finishing operations

In these systems, AGEFLOC 1071-AP is often used alongside inorganic coagulants such as polyaluminum chloride (PAC), aluminum sulfate, or ferric salts. The coagulant destabilizes fine particles, while AGEFLOC 1071-AP rapidly bridges them into large, dense, and shear-resistant flocs, which can be removed via sedimentation, dissolved air flotation (DAF), or mechanical filtration. This leads to:

• Effective removal of oils, greases, and suspended solids

• Significant reduction in COD, BOD, and color

• Improved process water recycling and reuse

• Stable biological treatment operation and reduced operational downtime

3. Sludge Conditioning and Dewatering

AGEFLOC 1071-AP is highly effective in sludge conditioning, providing strong floc formation and efficient dewatering for primary sludge, waste activated sludge, chemically precipitated sludge, and mixed municipal–industrial sludges. Its applications include:

• Belt filter presses

• Decanter centrifuges

• Screw presses

• Plate-and-frame filter presses

• Gravity thickeners

The polymer forms large, porous flocs that release bound water efficiently under mechanical force. Advantages include:

• Higher dry solids content in sludge cake

• Lower polymer dosage per ton of dry solids

• Reduced energy consumption during dewatering

• Improved equipment throughput and performance

• Lower sludge disposal costs

Its cationic nature ensures that even sludges with high organic content or filamentous bacteria are efficiently flocculated and dewatered, providing reliable and predictable performance.

4. Papermaking Industry

In the paper and pulp industry, AGEFLOC 1071-AP is used as a retention and drainage aid, particularly for paper grades with high filler and fiber content. Its key benefits include:

• Improved retention of fibers, fillers, and fines

• Faster drainage on the wire section

• Reduced solids in white water

• Enhanced paper formation and uniformity

• Higher machine speed and overall productivity

Additionally, AGEFLOC 1071-AP is effective for papermaking sludge dewatering, which contributes to cleaner water reuse and lower wastewater discharge loads.

5. Food and Beverage Applications

In food and beverage processing plants, AGEFLOC 1071-AP is applied to clarify wastewater containing fine suspended organic solids, proteins, and colloids. It enhances:

• Sedimentation of organic particles

• Removal of suspended solids and turbidity

• Reduction of BOD/COD load before biological treatment

This improves treatment efficiency, reduces chemical consumption, and supports water reuse in brewery, dairy, and meat processing effluents.

6. Oilfield and Petrochemical Industry

AGEFLOC 1071-AP is used in oilfield produced water and refinery wastewater treatment. It efficiently flocculates fine solids, oil droplets, and residual polymers, improving separation efficiency and supporting water reinjection, reuse, or safe discharge. Its performance in these applications helps maintain compliance with strict environmental standards while enabling sustainable water management.

7. Key Advantages of AGEFLOC 1071-AP

• High flocculation efficiency at low dosage

• Strong bridging for shear-resistant flocs

• Effective in high-organic-content sludges

• Wide pH and temperature adaptability

• Compatible with inorganic coagulants such as PAC, alum, and ferric salts

• Stable and reliable performance under fluctuating process conditions
