  • Who makes praestol ® flocculants?
  • Praestol ® flocculants (655 BC-S, 859 BS, 658 BC-S, 854 BC-S, 858 BS) are made by Ashland (USA) and XPC flocculants by Kemira (Sweden). Table 1 shows the individual types of chemicals together with their characteristic properties. For the test, flocculants were dissolved in distilled water to reach a 500 mg/l stock solution.
  • Which cationic polyacrylamide flocculants are used in the study?
  • Ten cationic polyacrylamide (CPAM) flocculants (each with different molecular weight and charge—see Table 1) were used in the study. Praestol ® flocculants (655 BC-S, 859 BS, 658 BC-S, 854 BC-S, 858 BS) are made by Ashland (USA) and XPC flocculants by Kemira (Sweden).
  • Which polyacrylamide cationic flocculant is used for SS thickening?
  • Polyacrylamide flocculants are most often used in wastewater treatment and utilization of sewage sludge to improve the separation of the solid and liquid phases [ 13, 14, 15 ]. In our earlier experiments, different concentrations of the polyacrylamide cationic flocculant Praestol 650 (PAM) were used for SS thickening before batch-mode AD.
  • How effective is polymer-assisted flocculation?
  • Most recent studies on polymer-assisted flocculation have reported exponentially decreasing settling profiles, indicating a high flocculant effectiveness. The slope of the initial linear part of the settling profile is called the initial settling rate (ISR), which determines the initial recovery of clean water from a suspension.
