Process for Reducing Selenium from Ion-Exchange Brine |
| abstract |
The present invention entails a method of treating an ion exchange regenerant stream containing selenate and removing the selenate from the regenerant stream through an oxidation-reduction process where selenate is reduced to selenite and the selenite is adsorbed onto an adsorbent which, in one embodiment, comprises iron oxide or iron oxyhydroxide. In particular, the method includes catalytically reducing the selenate to selenite in a selenate reduction reactor by reacting iron powder with the selenate in the presence of a nickel powder, which functions as a catalyst, to form selenite which is then adsorbed onto the iron oxide or iron oxyhydroxide. |
