  • How is an anionic polyacrylamide flocculant synthesized?
  • In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
  • What are polysaccharide flocculants based on?
  • The polysaccharides flocculants based on starch, chitosan, cellulose, and their derivatives are listed in Table 1. Polysaccharide flocculants used in water and wastewater treatment.
  • Why is polyacrylamide used in water treatment and sludge dewatering?
  • Polyacrylamide and its copolymers are extensively employed in water treatment and sludge dewatering. The efficiency of flocculation is influenced by factors such as the type of flocculant used, its molecular weight, and its concentration in the water suspension.
  • Which flocculants are used in wastewater treatment?
  • Summary of chitosan, cellulose, and alginate-based flocculants used in the treatment of wastewater TOC, total organic carbon; CNC, cellulose nanocrystal. Stimuli-responsive polymers are a class of macromolecules that undergo conformational changes and switch their solubility when the right stimulus is applied.
