Flocculation & Coagulation Products

Anionic polyacrylamide (APAM) is the negatively-charged, very-high-molecular-weight PAM grade — the largest-volume flocculant for clarification and mineral processing. It excels with inorganic or post-coagulation (positively-charged) suspended solids in neutral-to-alkaline water. It is one of the three grades in the polyacrylamide overview (compare cationic PAM (CPAM)…

Cationic polyacrylamide (CPAM) is the positively-charged PAM grade and the flocculant of choice for sludge and biosolids dewatering. Its positive charge neutralizes the negative surface charge of organic solids and builds robust, shear-resistant flocs that release water on a belt press or centrifuge. It is…

Nonionic polyacrylamide (NPAM) is the near-neutral PAM grade — an acrylamide homopolymer that flocculates by bridging and is prized for its salinity tolerance and performance across a wide pH range. It is the grade of choice where charged polyelectrolytes lose effectiveness. It is one of…

A long-chain polymer that bridges fine particles into settleable flocs at very low dose. It is used as a flocculant and coagulant aid for solid-liquid separation in water and wastewater treatment and as a retention and drainage aid in papermaking.
