flocculant - Schlumberger Oilfield Glossary

  • 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 polyacrylamide based flocculants?
  • Polyacrylamide-based flocculants constitute the most important group of water-soluble polymers commercially applied in harvesting freshwater and marine microalgae from their suspensions. This is primarily due to the high reactivity, hydrophilic nature and relatively low costs associated with their monomer acrylamide .
  • Which polyacrylamide variant has the highest flocculation efficiencies?
  • Polyacrylamide variants 71,305 and 71,303 possessing low to medium charge densities and medium to high molecular weights offered the highest flocculation efficiencies of 85.3% and 89.9% at the lowest flocculant doses 3 mg/L and 4 mg/L, respectively.
  • Are polyacrylamide flocculants toxic?
  • While most polyacrylamide flocculants are stable and non-toxic, some may leave behind acrylamide residues that are anticipated to be neurotoxic, potentially carcinogenic and generally exhibit high toxicity towards aquatic life .
