Abstract
Disclosed is a process for reclamation of waste fluids. A conditioning container is employed for receipt of waste material on a continuous flow for treatment within the container by immersible transducers producing ultrasonic acoustic waves in combination with a high level of injected ozone. The treated material exhibits superior separation properties for delivery into a centrifuge for enhanced solid waste removal. The invention discloses a cost efficient and environmentally friendly process and apparatus for cleaning and recycling of flowback, or frac water, which has been used to stimulate gas production from shale formations. The apparatus is mobile and containerized and suitable for installation at the well site.
