  • 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 .
  • 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 .
  • How much polyacrylamide flocculant do you need?
  • In general, polyacrylamide flocculants with very low charge densities below 10 mol% required very high flocculant doses above 45 mg/L to effectively flocculate the marine algae cells.
  • Are cationic polyacrylamides effective at a fixed flocculant dose?
  • The efficiency of four high molecular weight cationic polyacrylamides FO 4450, FO 4650, FO 4800 and FO 4990 at a fixed flocculant dose was analyzed by Garzon-Sanabria et al. on marine microalgae Nannochloropsis salina cultures in the presence and absence of algogenic organic matter.
