Selecting PAM for Sewage Wastewater Treatment
Most sewage sludge dewatering programs begin with cationic polyacrylamide, but a complete trial plan may also compare anionic and nonionic products depending on the process location.
Cationic PAM
Commonly used for waste activated sludge and organic-rich sludge. See a focused reference at cationicpolyacrylamide.com.
Anionic PAM
Often relevant for mineral solids, primary clarification aids, and some industrial wastewater streams. See anionicpolyacrylamide.com.
Nonionic PAM
Useful where ionic interaction should be limited or water chemistry is unusual. See nonionicpolyacrylamide.com.
