The drinking water industry is faced with microbial contaminants that are challenging to removeor inactivate with conventional treatment technologies. Pulsed arc electrohydraulic discharge(PAED) is a direct plasma technology that can treat water by several mechanisms concurrently.These include: shock waves, ultraviolet (UV) irradiation, radical reactions, electron processes, ionic reactions,and thermal dissociation. Batch-scale experiments using a 0.7 L PAED reactor were conductedto evaluate Escherichia coli and Bacillus subtilis inactivation with PAED. Median E. colireductions of 0.05, 1.3, and 2.4 log were observed after the approximately 15, 60, and 80 secondsof treatment with PAED; concurrently, B. subtilis reductions of 0.4, 3.1, and 4.6 log respectivelywere observed. PAED is an innovative technology because it offers concurrent treatment ofchemical and microbial target compounds. The emergence of PAED as a viable treatmenttechnology will offer another effective barrier for the protection of public health. Includes 8 references, figure.
