  • Who makes acrylamide based flocculants?
  • SNF is the world’s leading manufacturer of water-soluble polymers and acrylamide monomer, which is the primary ingredient for polyacrylamide-based flocculants. Together with its parent company, The SNF Group, SNF has major production sites in North America, Europe, and Asia, with many smaller plants and trading offices located worldwide.
  • 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 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%.
  • 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.
