![]() Hydrocyclones and Dewatering Screen System. ![]() The following key pieces of equipment are required for sediment removal and dewatering operations: Silt curtains can be used to keep solids from reaching the intake as dredging continues the silt curtain can be moved as dredging progressed from the east end towards the westģ. Progress surveys in conjunction with flow monitoring, solids sampling of the dredge slurry, dewatered sediments and return flow are used to determine dredge quantity volume. Depending if you have a liner or not, select a dredge cutter or auger head equipped with wheels to prevent the head from disturbing the sand layer or liner.Ģ. This method would include hydraulic dredging of the sediments from the slurry pond pumping of the sediments to the landfill site mechanical dewatering of the sediments at the landfill direct placement of dewatered sediments into the landfill and a water treatment and clarification process for treatment of process effluent to meet the 200 ppm TSS standard.ġ. The process uses mechanical separation and dewatering of coarse sediments with screens and the addition of polymers to enable mechanical dewatering of the fine sediments.
