Abstract

Key findings

  • The presence of cationic starch enhances the flocculation of GCC, leading to improved settling rates.
  • MFC addition further improves the flocculation behavior of GCC, resulting in more efficient settling.
  • The combination of cationic starch and MFC leads to a significant reduction in power density, indicating improved energy efficiency.
