Coagulant Recovery from Water Treatment Residuals: A
coagulants, sludge, water treatment Abstract: Conventional water treatment consumes large quantities of coagulant and produces even greater volumes of sludge. Coagulant recovery (CR) presents an opportunity to reduce both the sludge quantities and the costs they incur, by regenerating and purifying coagulant before reuse.
Conventional water treatment consumes large quantities of coagulant and produces even greater volumes of sludge. Coagulant recovery (CR) presents an opportunity to reduce both the sludge quantities and the costs they incur, by regenerating and purifying coagulant before reuse. Recovery and purification must satisfy stringent potable regulations for harmful contaminants, while remaining

Using Acid Mine Drainage to Recover a Coagulant from Water
We evaluated the recovery of aluminum from water treatment residuals by acidification using acidic coal mine drainage as an extraction solution. The water treatment residuals had Al and total Fe concentrations of 1.2 and 1.3%, respectively, based on mass. The influence of contact time of the mine water with the water treatment residuals and the percent of excess sulfate were assessed.
Highlights Acid recycling is mandatory for economic coagulant recovery. ED coagulant recovery has the same OPEX as conventional dosing of virgin coagulant. UF coagulant recovery reduces OPEX for alum dosing in potable treatment by 40%. DD associated OPEX must be lowered by >40% to equal or reduce virgin alum costs. OPEX for selective recovery of ferric coagulants exceeds those for virgin ferric.
Polyacrylamide
Product Cationic polyacrylamide (CPAM) is a water-soluble polymer polyelectrolyte, easily soluble in water, and insoluble in organic solvents such as ethanol and acetone. The molecular chain has cationic groups and active adsorption groups.
Anionic polyacrylamide Polyacrylamide is, simply called PAM, a water- soluble high polymer and widely used in petroleum, paper-making, metallurgical, textile, chemical and environment protection fields. There are three categories of anionic, cationic and non-ionic type. Application introduction PAM series products contain affinity radical and they can dissolve in water easily and play the role

- What is partially hydrolyzed polyacrylamide (PHPA)?
- Partially hydrolyzed polyacrylamide (PHPA), consisting of neutral acrylamide and anionic acrylate groups, is suitable for use in water with <25,000 mg/L TDS 12, 15.
- Which polymer is used to produce partially hydrolyzed polyacrylamide (HPAM)?
- PAM is used to produce partially hydrolyzed polyacrylamide (HPAM), which is linear, anionic, water-soluble, stable, polymeric, and high molecular weight chain of acrylamide (C 3 H 5 NO) monomers (Bao et al., 2010; Braun et al., 2025; Liu et al., 2016; Xiong et al., 2018).
- Does polyacrylamide hydrolyze under acidic conditions?
- As reported by Muller et al., polyacrylamides undergo hydrolysis under acidic conditions to yield poly (acrylamide-co-acrylic acid). Amide groups will completely hydrolyze under conditions of appropriately low pH, and polymer weight will remain relatively stable during hydrolysis, as the following formula , , .
- What is thermal stability of water soluble polyacrylamide (PAM) and partially hydrolyzed polymers?
- Thermal stability of water-soluble polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) polymers under various solution conditions have been studied utilizing Quantum Mechanics Density Functional Theory (DFT) computational modeling method.
