The U.S. Army is continuing their investigation of potential processes for treating or disposing of the process waste stream red water resulting from TNT production and purification. Thirty technologies for treating red water were proposed for evaluation. The preliminary evaluation used a decision tree to determine the potential of each process to provide a technically, economically, and environmentally acceptable method for disposing of waste products from the purification of crude TNT. After the preliminary evaluation, 14 technologies were identified for secondary evaluation. The secondary evaluation used several criteria and a point assessment scale to identify the following four processes for further evaluation 1 Wet air oxidation 2 Circulating-bed combustion 3 Slagging rotary kiln and 4 Submerged combustion. Wet air oxidation involves oxidation with air or oxygen at temperatures between 175 and 327 C and pressures between 2,069 to 20,690 kilopascals. Circulating bed combustion involves thermal treatment of wastes at temperatures between 800 and 1000 C 1472 and 1832 F. Incineration by slagging rotary kiln is a process in which wastes are incinerated in a rotary kiln at temperatures greater than those used in standard rotary kilns. The submerged combustion process is similar to the slagging rotary kiln in that higher temperatures are maintained to melt the salts and to produce a slag that encapsulates the ash constituents and thus exhibits greater resistance to leaching.
