What is a CSE?
When traditional dredging equipment is utilized, much of the excess water removed with the sediments is free water. This free water, which is typically removed (in dewatering processes) contains contaminants and must be treated prior to discharge. All water that is or cannot be removed from the excavated mud, must be disposed of with the contaminated sediments. As a result, the recovery of sediments with minimal moisture has significant economic advantages. A Contaminated Sediment Excavator (CSE) is a specialized sediment removal bucket that is designed to recover low moisture content sediments with a reduction in turbidity generated doing the excavation process.
