This post concludes the discussion on solids dewatering-transport-disposal. This series was started with post B-FSM-152.

Key Takeaway Items from the D-T-D training Module

1. All solids handling systems should start with identification of the proper disposal location
2. Dewatering is removal of free liquids from sand slurry to minimize disposal volume

• Open (non-hazardous) or closed (hazardous) dewatering systems

3. Final disposal site determines transport method

• As slurry in piping or as dewatered sand in bin/bag

4. Four main groups of locations

• Landfill disposal
• Overboard discharge
• Slurry fracture injection (SFI)
• Unique methods

5. Environmental regulations concerning specific contaminants is primary factor in disposal route
