1. A system for treating harmful biological contaminants comprising:
one or more plasma probes for treating harmful biological contaminants in water flowing through each probe, where each probe comprises dielectric barrier discharge elements;
backpressure control means for adaptively controlling backpressures exerted on the elements when a backpressure between the elements and a reservoir exceeds a threshold; and
an ionization section for further treating the harmful biological contaminants in the water.
