<p>A process and system for the reduction of nitrate to nitrogen in a fluid medium. A bed of anaerobic bacteria (18) fed by a carbon source (20) are used for nitrate reduction. The addition rate of the carbon source and process residence time are controlled using the oxidation reduction potential of the fluid medium to achieve a desired level of nitrate reduction. An industrial process control system (50) may be used to monitor inputs and control outputs. A column of suspended beads may be used as the bacterial bed.</p> |
