Abstract : Key questions addressed in this study are: (1) What is the efficiency and projected cost for electron beam decontamination of red water and other waste water streams? (2) Does induction accelerator technology with associated high electron irradiation dose rates influence process efficiency? Reported results show that dose rate indeed affects decontamination efficiency. However, dose rates, at the lower end of the range which is practical for large scale induction accelerator systems, are as efficient as competing continuous electron beam systems. Said simply, no significant penalty is implicit in the application of this compact, reliable and low cost technology. The projected dose requirements for red water decontamination is 630 Mrads with a projected treatment cost of $1.50 per gallon. This is comparable to the cost of incineration; consequently. This technology does not present an attractive alternative. It may, however, offer an attractive means for decontamination of pink water which has composite contaminant concentrations of order 200 ppm. This observation is based on reported studies of a variety of volatile organics at concentrations between 40 and 400 ppm. Here the dosages required for reductions by a factor of ten range between 0.73 and 2.7 Mrads and the associated treatment costs are projected as $1.70 to $6.40 per thousand gallons. This is much less costly than competing conventional and advanced technologies. Induction accelerator technology as developed at SRL would, therefore, offer a cost effective system which is scalable to hundreds of millions of gallons per year. -BKA
