Abstract

A process for separating a sludge stream containing particulate matter into a stream containing predominantly clarified water and a stream containing predominantly particulate matter is disclosed. The process involves passing the sludge stream through a solid reagent contactor bed composed of solid reagent tablets having a copolymer composition for particle aggregation as described in U.S. Pat. No. 8,076,391. The dissolution of the solid reagent tablets into the sludge stream treats the sludge and makes it amenable for the speedy settling of concentrated sludge at the bottom of a sludge concentrator tank leaving a relatively clean water phase to rise to the top. The process is particularly useful for recovering water from mining sludge.
