Adventus Remediation Technologies Inc. (formerly Grace Bioremediation Technologies), has developed a highly efficient, stable denitrification technology that has been proven at full scale. At a facility near Baltimore, a denitrification reactor has been in continuous operation since 1998 for removal of 1,500 – 3,000 mg/L NO3-N from process water. This reactor has a very basic design, with no automation. pH adjustment and methanol addition is done on a dose basis (i.e., without continuous monitoring to match acid and methanol dosing to actual pH and NO3-N concentration). Although the waste stream varies significantly in NO3 and NH4 as well as pH, the process remains stable and continues to be very resistant to changes in the feed. If required, a fully automated system can be designed as well.
