摘要
A system and method removes contaminated sediments during dredging operations to minimize the dispersion of particulate matter that normally occurs during conventional mechanical or hydraulic dredging operations. The system uses a specially designed pressure controlled enclosure or enclosed excavator that houses a mechanical bucket. The enclosure is designed to capture suspended particles that are dispersed into the water column during the mechanical dredging process. The system also includes the use of a self-contained membrane filtration treatment vessel to remove fine particulate matter from dredge drainage waters collected in the process.
