Another advantage of the present invention is that scandium recovery is possible from any feed stream including acidic solutions or pulps such as uranium tailings, red mud, and waste sludge containing zirconium, titanium, or compounds including zirconium or titaniumWaste Water Treatment Activated sludge process The Activated Sludge Process in the one of the waste watertreatment process Activated sludge process was developed in England in 1914 and was so named because it involved the production of an activated mass of microorganisms capable of aerobically stabilizing the organic content of a waste.
