Quarry water is a solution of water and suspended aggregate particles, and as part of dewatering, the slurry or wastewater must be thickened in a special tank to allow the sediment to separate naturally from the lighter water. This happens in conical thickening or sediment tanks, where slurry is placed in storage to allow the silt to settle out.
