Abstract
Dense sludge is an innovative and improved method for treating acidic metal bearing streams in a manner which minimizes volumetric generation of sludge for disposal. In the Dense Sludge process, the alkali source is combined with recycled sludge before being introduced into raw water influent, thus forming metal particles with a low affinity for water. The sludge density of clarifier underflow has in some cases increased from the usual 1--2% to nearly 35% solids. This paper will describe installation and operating data from a 9,000 gpm Dense Sludge AMD Treatment Facility at a coal mine in Northern West Virginia.
