Overview
60% cationic degree coagulant aid is a specialized polyacrylamide (PAM) derivative with exceptionally high positive charge density. As a water-soluble polymer, it serves as a critical component in modern water treatment processes where charged particle neutralization and bridging are required. The 60% ionic degree indicates the proportion of cationic monomer units in the polymer chain, making it particularly effective for treating negatively charged colloidal suspensions commonly found in industrial effluents and municipal wastewater. Its development represents an advancement over conventional coagulant aids with lower charge densities.
Physical and Chemical Properties
This coagulant aid typically appears as white free-flowing granules that dissolve completely in water to form viscous solutions. The high molecular weight (5-15 million Daltons) creates long polymer chains that effectively bridge between particles. Key characteristics include shear stability, pH tolerance between 3-10, and minimal residual monomer content (<0.1%). The product's effectiveness stems from its quaternary ammonium groups which provide strong electrostatic attraction to negatively charged contaminants. Unlike anionic or nonionic PAMs, this cationic form demonstrates superior performance in organic-rich wastewater where zeta potential neutralization is crucial for floc formation.
Main Applications
Primary applications include municipal wastewater treatment plants for enhancing primary clarification and sludge dewatering. In industrial settings, it's widely used in food processing wastewater treatment, textile effluent clarification, and mining operations for tailings management. The product shows particular effectiveness in biological wastewater treatment systems, where it improves sludge settling characteristics in secondary clarifiers. Paper mills utilize it as a retention aid and drainage promoter. Oilfield applications include produced water treatment and drilling fluid conditioning. Dosage typically ranges from 0.1-10 ppm depending on system requirements.
Safety and Storage
While non-toxic at recommended usage levels, the dry powder can cause eye and respiratory irritation. Appropriate PPE including dust masks and goggles should be worn during handling. The product is non-flammable but should be stored away from strong oxidizers. Proper storage involves keeping the product in its original sealed packaging in a cool (below 30°C), dry environment. Shelf life is typically 12 months when stored correctly. Prepared solutions should be used within 48 hours as viscosity decreases over time due to polymer chain degradation. Spills should be contained and cleaned with dry methods before wet mopping.
B2B Procurement Guide
When procuring 60% cationic coagulant aids, verify supplier certifications including ISO 9001 and relevant water treatment chemical approvals. Request product technical data sheets with detailed specifications of ionic degree, molecular weight, and solubility characteristics. For large-volume purchases (container loads), consider requesting factory audit reports. Key procurement factors include batch-to-batch consistency, dissolution rate, and floc formation performance in your specific wastewater matrix. Many suppliers offer free sample quantities for jar testing. Payment terms for industrial buyers typically range from 30-60 days L/C for established business relationships.
