Process For Removing Heavy Metals From Water

US Patent:
5266210, Nov 30, 1993
Filed:
Apr 15, 1992
Appl. No.:
7/869239
Inventors:
Ronald J. McLaughlin - Arvada CO
Assignee:
McLaughlin Water Engineers, Ltd. - Denver CO
International Classification:
C02F 162
US Classification:
210710
Abstract:
Wastewater contaminated with heavy metals is treated in a multi-stage process. In a first stage, wastewater is treated with an effective amount of calcium oxide and/or calcium hydroxide in the form of lime to adjust the pH so that various metals in the water become insoluble. Gypsum formation may also occur if sulfate ions are present in the wastewater. In a second stage, an effective amount of sodium carbonate is added in the form of soda ash to allow formation of calcium carbonate. In a third stage, a coagulant, preferably a polymer, is added to facilitate the formation of a sludge comprising heavy metals, gypsum and calcium carbonate. In a final stage, the pH of the resulting effluent may be adjusted with a suitable acid, such as hydrochloric acid, to attain acceptable discharge requirements. The sludge formed is substantially stable and dewatered and has low toxic metal leaching characteristics.
