What is residual contamination and how can Seaways Mobile Water Treatment Platform remove this contamination?
Due to the nature of the dredging process, a residual fluffy layer of low density highly contaminated sediment will resettle to the bottom of the waterway. This layer is source of contamination that can readily migrate to downstream areas, is highly available to enter the food chain and prevents cleanups from achieving low residual concentrations in the remaining sediments. 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.
