The drinking water industry is faced with microbial contaminants that are challenging to remove
or 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 conducted
to evaluate Escherichia coli and Bacillus subtilis inactivation with PAED. Median E. coli
reductions of 0.05, 1.3, and 2.4 log were observed after the approximately 15, 60, and 80 seconds
of treatment with PAED; concurrently, B. subtilis reductions of 0.4, 3.1, and 4.6 log respectively
were observed. PAED is an innovative technology because it offers concurrent treatment of
chemical and microbial target compounds. The emergence of PAED as a viable treatment
technology will offer another effective barrier for the protection of public health. Includes 8 references, figure.
