Municipal

The Global Process is a cost effective and environmentally sound method of processing municipal waste pond sludge.  The dewatered solids can simply be landfilled or can be landspread as a soil amenity in conjunction with composting or without composting.  Lime can be added during the centrifuging to stabilize processed cake as well as prevent odor pollution during processing should this be a concern.

Dewatering

The Sharples horizontal, counter current flow, high solids, high 'g' force centrifuges provide rapid separation due to the density differential between the water and the solid particles within the feed matrix.

If required, flocculating polymers, mixed and stored in two agitated polymer tanks onboard the module, are injected into the feed prior to the centrifuge to aid separation.

Each of the centrifuges can process up to 264 U.S. gallons (1m³)/minute of feed and produces two process phases, dry cake and centrate. The dry cake is discharged to the conveyor system for subsequent disposal and the centrate is returned to the source.

Dredging

The Global Surgical Lagoon Pumper is a modern, silent, all-electric dredge designed for extremely accurate solids removal and low turbidity operation.

There are no hydraulics, and therefore no potential for hydraulic/diesel leaks and/or spills.

Dredging accuracy is controlled through the combination cable/winch guidance system and the cutterhead boom depth indicator.

All dredging functions are electronically controlled. Safety is enhanced, as the operator is not on the dredging unit while it is in operation.

Screening/Conditioning

Dredging materials pass along a floating pipeline and onshore to the screening/conditioning tank. Solids pass over a shaker screen for debris removal.

Screened debris falls onto a dewatered sludge conveyor for disposal. The rest of the stream enters the conditioning tanks for mechanical agitation or homogenization.
