  • 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.
  • 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.
  • 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
  • What is an anionic polyacrylamide?
  • Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
