Application Scenarios
Suitable for sludge dewatering operations using belt filter presses, plate-frame filter presses, centrifuges and screw presses across municipal and industrial wastewater treatment plants.
Applicable to primary sludge, waste activated sludge, mixed sludge, digested sludge and industrial sludges with varying solids content, organic fraction and dewatering characteristics.
Solutions
High-charge cationic polyacrylamide polymers optimize sludge dewatering by neutralizing negatively charged sludge particles and forming strong, compact flocs that release water efficiently. Grades are tailored to dewatering equipment type and sludge characteristics, delivering low cake moisture, high solids capture and reduced polymer consumption for lower operating and disposal costs.
• Low cake moisture content for reduced disposal volume and cost.
• High solids capture rate and clear filtrate return.
• Optimized for belt press, centrifuge, plate-frame and screw press.
• Wide range of cationic charge densities for different sludge types.
• Rapid floc formation for high-throughput dewatering operations.
• Low dosage requirement for cost-effective performance.
