Fundamental Study on the Ozone Posttreatment of Reverse Osmosis Permeates from Army Wastewaters.

Abstract

The ozonation process is demonstrated to be an effective means to remove trace amounts of organics that pass through the reverse osmosis (RO) process. The kinetics and the mechanism of the ozonation process have been studied to improve removal of these compounds from RO permeates. An extensive effort was made to develop methodologies for the analysis of trace organics in RO permeates as well as for the intermediates formed during ozonation of RO permeate. This involved the use of distillation, head space, and purge and trap methods for the concentration of volatile organic constituents and of the solvent extraction method for the concentration of intermediately volatile (i.e., GC volatile) and nonvolatile organics. Gas chromatography (GC) was used to determine the volatile and intermediately volatile compounds, whereas high pressure liquid chromatography (HPLC) was used for the nonvolatile compounds. (Author)
