Liquid Dicyandiamide Formaldehyde Resin – Polycationic Flocculating Agent for Papermaking Wastewater Treatment
High-efficiency polycationic flocculant for papermaking and industrial wastewater, improving water clarity, fiber recovery, and sludge dewatering.
Product Overview
This liquid Dicyandiamide Formaldehyde Resin polycationic flocculant is designed for papermaking and industrial wastewater treatment, providing rapid floc formation, improved water clarity, and efficient solids separation. It is suitable for white water clarification, fiber recovery, and sludge dewatering in paper mills.
- High cationic charge for effective destabilization of colloids
- Rapid formation of dense flocs
- Compatible with pH 6–9
- Reduces sludge volume and improves effluent quality
Bluwat Chemicals offers daily lab jar tests to recommend the optimal dosage based on real wastewater, ensuring reliable and reproducible results.
Cause
Papermaking wastewater contains high levels of suspended solids, colloids, and residual chemicals. Conventional coagulants often fail to remove fine fibers and micro-colloids, leading to:
- Poor water clarity
- Slow settling rates
- Excessive sludge volume
- Higher chemical consumption
Solution
This polycationic flocculant works via:
- Charge neutralization: destabilizes negatively charged fibers and colloids
- Adsorptive bridging: binds multiple particles into dense flocs
- Rapid floc formation: enables fast sedimentation and dewatering
- Improved retention and drainage: enhances papermaking efficiency
Recommended treatment sequence:
- Add Dicyandiamide Formaldehyde Resin
- Adjust pH if necessary (6–9)
- Add PAM to accelerate floc settling
