Which two dewatering practices treat sediment-laden water after being pumped?

The two dewatering practices that effectively treat sediment-laden water after being pumped are the filter bag and the portable sediment tank.

A filter bag is commonly used in erosion and sediment control to capture sediment from water that has been pumped from construction sites or other areas where sediment is a concern. The water flows through the filter bag, which has a fabric that allows clean water to pass while trapping sediment particles, thereby helping to prevent them from entering the stormwater system or nearby water bodies.

Similarly, a portable sediment tank is designed to settle out sediment from the water that is being dewatered. When the sediment-laden water is pumped into the tank, heavier particles will settle to the bottom, allowing the clarified water to exit through a different outlet. This method enhances the treatment of sediment-laden water by physically removing sediment before it is discharged.

Both of these methods focus on treating the water post-pumping, effectively minimizing the risk of sedimentation in water bodies, which is crucial for protecting water quality and meeting environmental regulations.
