Nitrate Destruction Literature Survey and Evaluation Criteria

Remediation and recycling of inorganic acids and their green alternatives for sustainable industrial chemical processes

“…88 The industrial low acidic waste water discharges containing nitrate could be treated with the articial denitrication processes. 89 Some of these methods are: bio-mediated denitrication, [90][91][92][93][94][95] catalyzed chemical, [96][97][98][99][100][101][102] electrochemical methods, 96,[103][104][105][106][107] photocatalytic reduction, 108 and hydrothermal decomposition. 109,110 Although biological denitrication is a well-developed technology for converting nitrate to nitrogen, it is sluggish and difficult to manage, and the presence of other metal ions in the discharges inhibits bacterial growth.…”

Kinetics of reduction of nitric acid by electrochemical method and validation of cell design for plant application

“…To reduce the volume of high level liquid waste (HLLW) and to control the corrosion in 304 L stainless steel waste tanks during subsequent storage of concentrated waste solution, it is desirable to reduce the nitric acid concentration to a lower value. Among the denitration processes for the treatment of highly radioactive waste solutions, methods such as Nitrate to Ammonia and Ceramic (NAC) process, electrochemical destruction, biological denitration, calcination, hydrothermal and chemical reduction are significant and studies performed using these processes for the denitration of low/high level liquid wastes have been reported in literature reviews [1][2][3][4][5]. Biological denitration reduces nitrate to nitrogen or its oxides using a broad range of bacteria in the presence of reducing organic nutrients like methanol, methane, glucose and starch [6].…”
