  • Can cationic polyacrylamide emulsions with ultra-high concentration save transportation costs?
  • Cationic polyacrylamide emulsions with ultra-high concentration (CPAME-uhc) can obviously save transportation costs, but their molecular weight, solubility, and temperature/salt resistance need to be further improved. Therefore, this study attempted to improve the molecular weight of CPAME-uhc by optimizing the preparation conditions.
  • 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
