Lake Restoration

The primary purpose of dredging is to remove nutrient-rich (or
toxic) sediments or control rooted aquatic macrophytes while preserving
the natural fish habitat. Dredging to remove nutrient release from
sediment can be highly effective. A hydraulic dredge equipped with a
cutterhead is most commonly used for lake dredging. The cutterhead loosens
sediments and aquatic growth allowing it to be transported as slurry
through a floating pipeline from the lake for disposal.
Final disposal can be a problem as the dredgeate is difficult
to handle. Decant ponds must be built to allow dredged material to settle.
Dredging may not be an option if space is restrictive for these decant
ponds. Even if decant ponds are available, settling time extends the
project.
The
Global Process allows the dredgeate to be dried as it is being removed,
therefore decant ponds are not needed. If various areas are to be dredged,
the process system is simply moved from area to area. The dredge is
all-electric. There is therefore no chance of an oil or diesel spill. Also
the dredge is silent allowing it to work and not disturb area
residents.
