A vital issue in military and civilian water treatment is the persistence of pollutants that are difficult to remove via traditional physical, chemical, and biological treatment technologies. Advanced oxidation processes (AOP) are a viable treatment alternative that allow targeting of specific organic pollutants for removal prior to release or reuse of treated water. Many methods have shown positive potential at the bench scale, however, their relative effectiveness in real treatment trains is difficult to assess. To achieve viable technology transfer, bench-scale research needs to feed into pilot-scale and full-scale studies; and that cannot happen without well-established metrics and means of comparison. The goal of this research is to validate and compare the effectiveness of AOP technologies to degrade and eliminate contaminants so that their use in wastewater treatment trains for military and civil applications can be realized. To this end, several AOP that can effectively remove emerging pollutants from a treated wastewater effluent stream have been tested, enabling the water to be reused as potable fresh water. Reaction kinetics for the degradation of pollutants with eight AOP were monitored. With these results, the energy inputs required by calculating electrical energy per order (EEO) for each AOP as a potentially important metric for comparison was analyzed.
