  • 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.
  • Who bought polyacrylamide flocculant?
  • Commercial flocculant of polyacrylamide (PAM, MW of 2000–14,000 kDa) was bought from Aladdin Industrial Corporation (Shanghai, China). Anhydrous ethanol and acetone were supplied by Zhenqi Chemical Reagent Co., Ltd (Shanghai, China).
  • 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.
