The system, consisting of a McLanahan UltraSCRUB Modular Scrubbing Plant and McLanahan UltraSAND Plant, will help SunSkips limit construction waste from going to landfill. It also includes an HRT10 Thickener that will allow SunSkips to recycle most of its process water for reuse while limiting the volume of waste sent to the settling pond. The system will process construction, demolition and excavation waste as well as trommel fines.
The UltraSCRUB and UltraSAND will allow SunSkips to produce three aggregate products of varying sizes and one sand product from C&D debris streams. The raw material will be fed onto a single deck pre-screen module as part of the UltraSCRUB unit to separate fine sand particles before scrubbing. The sand will flow into the sump of the UltraSAND Plant and be pumped to a Hydrocyclone, where it will be washed to remove silt. The underflow of deslimed and partially dewatered solids will then discharge onto a Dewatering Screen to create a drip-free product that can be conveyed to a stockpile.
Meanwhile, the coarse aggregates that pass through the pre-screen module will be fed into the UltraSCRUB's Coarse Material Screw Washer module. The Coarse Material Screw Washer will remove wood, plastics, organics and other trash from the aggregate.. The aggregate will then pass over a double-deck sizing screen, sorting the product into 10 mm, 20 mm and +20 mm aggregate that will be discharged onto respective conveyors and stockpiled.
The effluent from the scrubbing and washing processes will be sent to a Thickener to concentrate the solids in the waste stream, immediately recovering reusable process water and limiting the material sent to the settling pond.
