Mobile Water Treatment Platform

“Providing for the Treatment of Excess Dredge Water and the Removal of Residual Contamination”

Seaway's development of a patented mobile water treatment plant provides the means to treat excess dredge water generated during dredging operations and to assist in the removal of residual contamination at sediment cleanup sites.

Excess Dredge Water Treatment

Free water generated during the excavation, transport, and dewatering of contaminated sediments must be contained and treated prior to disposal. Seaway has designed and tested a mobile barge-mounted water treatment operation that can be brought to any location along a waterway and used to treat excess waters collected during dredging operations. Mobile excess dredge water treatment eliminates the need for fixed land-based facilities.

Residual Contamination (Vacuum Sweep Technology)

During contaminated sediment dredging operations, residual contamination in the form of a fluffy, highly contaminated sediment layer is a source of contamination that prevents high efficiency cleanups and will migrate to downstream locations. Multiple dredging passes using conventional technologies have shown to be ineffective in removing this residual contamination. Seaway’s patented mobile water treatment plant, coupled with its cutter-less vacuum head technology, provides the means to Vacuum Sweep this residual fluff layer. Used in tandem with a dredging operation, Seaway’s Vacuum Sweep Operation provides the most effective means to remove sediment inventory and residual contamination.

Seaway’s Mobile Water Treatment System makes use of Pall Water Filtration Membrane Technology and Carbon Adsorption treatment (if needed) to provide treatment efficiencies unattainable using conventional excess dredge water treatment systems.
