A method and device for treating contaminated water where the device is portable. The method includes the steps of moving contaminated water into a first tank to settle out large solids such as cuttings and metallic particles while adding a pH modifier, a coagulant, and gaseous ozone. Moving the contaminated water into a second tank where the pre-treated water is subjected to an electro-coalescing process that subjects the water to a strong DC current as the water passes between several bi-metallic plates. After the electro-coalescing process the water may be filtered to remove the remaining solids resulting from the pre-treatment and the electro-coalescing process or the solids may be allowed to settle. The resulting water may then be re-used in the fracturing or drilling processes. |
