  • 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.
  • Which polyacrylamide variants require a lower flocculant dose?
  • Polyacrylamide variants with low charge densities below 25 mol% and medium charge densities below 45 mol% required dramatically lower flocculant doses between 1.66 mg/L to 5 mg/L to achieve harvesting efficiencies surpassing 50%.
  • 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 .
  • Can polyacrylamide based flocculants be detected at low concentrations?
  • This study opened the possibility to detect polyacrylamide based flocculants even at low concentrations in complex matrices, hence an application to environmental samples has become feasible.
