Abstract
Harmful biological contaminants are treated using plasma fields. The inventive techniques offer improved results over existing devices and methods.
Claims20
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.
