(733d) Electrocatalysts for the Simultaneous Removal of Nitrate and Ammonia from Wastewater
Electrochemical methods for separate removal of NO3- and NH3 has been extensively investigated [1, 3-5]. However, in this work, we demonstrate a new process that addresses both water pollutants simultaneously in an undivided flow cell that leads to a remarkable energy saving in the order of 35-65 % and 90 % less energy per grams of NO3- and NH3 removal, respectively. A new catalyst composition material is introduced to perform both NO3- /NH3 removal simultaneously. The concentration of NO3- andNH3 were measured according to the Environmental Protection Agency (EPA) standards, i.e., an UV-vis spectrophotometric based technique , and NH3 Ion Selective Electrode (ISE-THERMO), respectively. Effect of catalyst loading and other process operational conditions on the NO3- and NH3 removal rates were investigated. Findings of this work will be presented at the meeting.
