Recovery and reuse of filter alum and soda alum in a water-treatment plant. Technical report, 1984-1988

Technical Report ·
OSTI ID:6673264
A Sludge Thickening and Alum Recovery (STAR) system was developed for pollution control and resource recovery. The STAR system is composed of a dissolved air flotation (DAF) unit for sludge thickening, an acid reactor for filter alum recovery, an alkaline reactor for soda alum recovery, and two liquid-solids separators for removal of inert residues from the two reclaimed liquid alums. The report presents the technical data generated from a demonstration project. Both the reclaimed filter alum and reclaimed soda alum are as effective as their virgin equivalents for water purification and phosphate removal.
