System and method for water treatment |
| abstract |
A method for removing selenium from an aqueous stream comprises adjusting the pH of the aqueous stream to an acidic pH and mixing a galvanic reductant into the aqueous stream to form a first process stream, the aqueous stream having a first selenium level; separating at least a majority of the galvanic reductant from the first process stream after a retention time to form a recovered galvanic reductant stream and a second process stream; adjusting pH of the second process stream to pH 9 or higher to form a third process stream comprising precipitated particles; separating the precipitated particles from the third process stream to form a sludge stream and a treated aqueous stream having a second selenium level, the second selenium level being less than 10% of the first selenium level. |
