Blufloc C8020 Cationic Polyacrylamide Polymer Medium Charge CPAM Flocculant for Sludge Thickening and Wastewater Treatment
Blufloc C8020 Cationic Polyacrylamide Polymer
Medium Charge CPAM Flocculant for Sludge Thickening and Wastewater Treatment
Product Overview
Blufloc C8020 is a medium charge cationic polyacrylamide (CPAM) supplied as a white granular powder. It is a high molecular weight water-soluble polymer developed to improve solid-liquid separation processes in municipal and industrial wastewater treatment systems.
Compared with lower charge polymers, Blufloc C8020 provides stronger particle bridging and floc formation capability, allowing suspended solids and colloidal particles to aggregate into large, compact flocs. This significantly improves sedimentation, flotation and filtration efficiency.
Blufloc C8020 is widely used in sludge thickening, sludge conditioning and wastewater clarification processes. The product is particularly effective in systems where moderate sludge charge density requires balanced charge neutralization and polymer bridging.
Typical applications include municipal wastewater plants, textile dyeing wastewater treatment, paper mill sludge dewatering, mining water clarification and industrial wastewater treatment systems.
Key Advantages
★Strong Flocculation Performance
Blufloc C8020 produces large and stable flocs that improve solid-liquid separation efficiency in sedimentation tanks and flotation systems.
★Improved Sludge Thickening
The polymer enhances sludge structure and increases sludge concentration prior to mechanical dewatering processes.
★Optimized Charge Density
The medium charge structure provides balanced charge neutralization and particle bridging, allowing effective treatment in many wastewater types.
★Reduced Chemical Consumption
Due to its high molecular weight and optimized ionic properties, effective treatment can often be achieved at relatively low dosage levels.
★Easy Handling and Dissolution
The polymer dissolves easily in water and forms a stable polymer solution suitable for automated dosing systems.

Frequently Asked Questions (FAQ)
What is cationic polyacrylamide used for?
Cationic polyacrylamide is widely used as a flocculant in wastewater treatment, sludge dewatering and solid-liquid separation processes. It helps suspended particles aggregate into larger flocs that can settle or be filtered more easily.
What is the CAS number of polyacrylamide?
The CAS number of polyacrylamide is 9003-05-8.
What is the difference between CPAM, APAM and NPAM?
Polyacrylamide polymers are classified according to ionic charge:
- CPAM (Cationic Polyacrylamide) – used for sludge dewatering and biological sludge treatment
- APAM (Anionic Polyacrylamide) – used in mining, mineral processing and water clarification
- NPAM (Nonionic Polyacrylamide) – used in special industrial wastewater conditions
How is polyacrylamide solution prepared?
Polyacrylamide powder should be dissolved in water to prepare a 0.1–0.5% polymer solution before dosing into treatment systems.
How is the correct dosage determined?
The optimal dosage depends on wastewater characteristics such as suspended solids concentration and sludge composition. Laboratory jar testing is recommended to determine the best dosage.
