Optimization Guide for PAM Dosage by Sludge Type
April 23, 2026
In municipal and industrial sludge dewatering, the dosage of polyacrylamide (PAM) directly affects dewatering efficiency and operational costs. Overdosing leads to filter cloth clogging and increased cake moisture content, while underdosing results in poor solid-liquid separation. Based on sludge classification by characteristics and incorporating typical academic data (cationic PAM 5–7 kg/tDS, anionic PAM 0.5–1.0 kg/tDS, etc.), this paper proposes optimized PAM dosage ranges for different sludge types, aiming to provide a reference for process control in wastewater treatment plants.…
