Abstract: The invention is directed to apparatus for treating water by exposing the water to a pulsed plasma discharge. The pulsed plasma discharge is generated using a suitable electrode configuration to generate the plasma discharge in the fluid. Apparatus useful in the method may include a vessel, at least two electrodes for generating a plasma discharge in water, and a flow inlet and a flow outlet to allow water to be passed through the vessel. Also described is an in-line water treatment, where a pulsed plasma discharge is used in a pipe carrying moving water. Plasma based fluid treatment system may have many advantages in comparison to other treatment methods, such as very minimal maintenance, low operating power, and minimal pressure loss through the device.

Abstract: The present invention consists of a method of pre-treatment of adulterated water for distillation, including adulterated water produced during hydraulic fracturing (“fracking”) of shale rock during natural gas drilling. In particular, the invention is directed to a method of treating adulterated water, said adulterated water having an initial level of bicarbonate ion in a range of about 250 ppm to about 5000 ppm and an initial level of calcium ion in a range of about 500 ppm to about 50,000 ppm, said method comprising contacting the adulterated water with a non-thermal arc discharge plasma to produce plasma treated water having a level of bicarbonate ion of less than about 100 ppm. Optionally, the plasma treated water may be further distilled.
