This study developed and evaluated a non-coagulant dredged sediment treatment system as an eco-friendly river dredging and management technology. From 2014 to 2023, heavy rain damage in South Korea amounted to approximately 2.8 trillion KRW, with a sharp increase since 2020. River dredging has been recognized as a crucial countermeasure, and this study aimed to minimize the environmental impact of conventional dredging methods by introducing a non-coagulant treatment system. The developed system utilizes a remotely operated vehicle (ROV) to suction dredged sediment, which is then processed through sedimentation and filtration to separate solids and discharge treated water. Field tests were conducted in Seohwa Stream, Okcheongun, Chungcheongbuk-do. Results showed that the turbidity increase within the ROV operation area was minimal at 3.8%, and the suspended solids (SS) removal rate was 100%. Additionally, the system is akinetes discharge concentration was confirmed to be 0 cells g-1, demonstrating its effectiveness in water quality restoration. These findings confirm that the non-coagulant dredged sediment treatment system reduces environmental impact while ensuring efficient dredging and water quality enhancement. The proposed technology is expected to serve as a sustainable solution for river dredging and management.
