Groundwater treatment, advanced

Operating costs associated with advanced oxidation systems are a function of capacity. One Ultrox unit installed in New York for groundwater treatment of trichloroethylene (TCE) and toluene had a capital cost of approximately 1 million with a 3900-gal reactor capacity and a 250-gal/min flow through capacity. Operating costs for the unit are approximately 1.57 per 1000 gal treated at the flow rate of 250 gal/min (D124629, pp. 736-737).

Data estimating 2-hexanone concentrations in water are sparse. 2-Hexanone was identified in one of three groundwater samples at a concentration of 87 pg/L (ppb) near a hazardous waste site in Florida (Myers 1983). This compound was also identified in a study of drinking water concentrates and advanced waste treatment concentrates (Lucas 1984).

Micro-, ultra-, and nano-filtration can separate smaller particles using media with defined porous sizes (i.e., 10 1—1 pm in microfiltration, 10 2—10 pm in ultrafiltration, and 10 3— 10 2 pm in nanofiltration). Residual colloidal and suspended solids can be removed by microfiltration. Selected salts, most organic compounds, bacteria, protozoan cysts, oocysts and viruses are removed by nanofiltration, so that the treated water will be disinfected. This advanced filtration is used for the treatment of effluents for indirect potable reuse applications such as groundwater injection, water softening, decoloriza-tion, or removal of micropollution.

Our initial work in automating laboratory analysis of radionuclides in nuclear waste has now advanced to the development of sensors and instruments for nonlaboratory settings. Our sensor for Tc in groundwater was selected for prototype engineering development, and a field test was conducted at the Hanford site in September 2002. This unit successfully quantified the Tc activity in Hanford groundwater samples. The automated Tc analyzer has been under development for use at the Hanford site, and was selected in a conqietitive process for incorporation into the Hanford Waste Treatment Plant.
