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.

Abstract translation: 本发明包括一种预处理掺杂的蒸馏水的方法，包括天然气钻井期间页岩的水力压裂（“压裂”）时产生的掺杂水。 特别地，本发明涉及一种处理掺假水的方法，所述掺杂的水具有在约250ppm至约5000ppm的范围内的碳酸氢根离子的初始水平和约500ppm范围内的钙离子的初始水平 所述方法包括使掺杂的水与非热电弧放电等离子体接触以产生具有小于约100ppm的碳酸氢根离子水平的等离子体处理的水。 任选地，可以进一步蒸馏等离子体处理的水。
