  • Does polymeric aluminum chloride and polyacrylamide dewater sludge?
  • Sludge dewatering is governed by chemical potential gap depicted by Flory-Huggins theory. Thermodynamic mechanisms of sludge dewatering by chemical conditioning was revealed. This study investigated the combined effects of polymeric aluminum chloride (PAC) and polyacrylamide (PAM) on sludge dewatering, aiming to unveil underlying mechanisms.
  • Can polyacrylamide coagulation improve sludge dewatering performance?
  • Enhancing sludge dewatering can effectively reduce the operational costs of wastewater treatment plants. In the present study, a synergistic process combining polyacrylamide (PAM) coagulation with Fe 2+ /CaO 2 Fenton-like oxidation was proposed to improve the performance of sludge dewatering.
  • Does polysaccharide sludge affect dewatering performance?
  • Similarly, a higher polysaccharide content in the raw sludge indicates lower dewatering performance ( Li et al., 2012 ). To address this issue, PAM is added to act as a netting and sweeping agent. It adsorbs negatively charged colloidal particles and collects and nets fine particles in the water.
  • What is a good dosage for sludge dewatering?
  • Considering both dewatering performance and cost-effectiveness, a PAM dosage of 5.0 mg/g DS was chosen for both pre-addition and post-addition in the composite system. Fig 2.
