20110198276 | SYSTEM FOR REMOVAL OF CONTAMINANTS FROM INDUSTRIAL STREAMS - A method and system for removing from an aqueous system which is contaminated therewith: (1) mercury present as colloids, ions and/or organically bound compounds, and (2) hydrocarbons solubilized, dispersed, and/or emulsified in the said system. Pursuant to the invention the aqueous system to be treated (such as “produced water”)is passed successively through three filtration stages. The first filtration stage is provided with absorption media which effects reduction/removal of dispersed organically bound mercury species and of the dispersed and partially dissolved hydrocarbon phases, as well as of some colloidal mercury and other dissolved metallic species. The second filtration stage utilizes a salt modified reticulated granular filtration media for reduction/removal of slightly dissolved hydrocarbon phases, mercury in colloidal and ionic form and other dissolved metals. The third filtration stage is a polishing stage, which serves to further reduce by electroless or voltaic reduction residual elemental mercury and/or residual colloidal and ionic mercury. At this third stage metallic mercury is incorporated into a metallic matrix from which the mercury may preferably be recovered. | 08-18-2011 |
