  • Can high molecular weight cationic polyacrylamides improve microalgae biomass recovery?
  • Hence, small doses of high molecular weight cationic polyacrylamides can substantially enhance microalgae biomass recoveries from large-scale wastewater pond abundant in poorly-separable microalgae colonies . 3. Key challenges 3.1. Choosing an appropriate biomass recovery technology
  • 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.
  • Why are cationic polyacrylamides used in microalgae culture?
  • High charge density and high molecular weight linear cationic polyacrylamides typically offered superior harvesting efficiencies in various microalgae cultures by diminishing the electronegativity of cell surfaces and bridging between the cells to bring about aggregation.
  • 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.
