Enhanced water treatment for reclamation of waste fluids and increased efficiency treatment of potable waters
View Patent ↗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.
1. A process for treating flowback water including the steps of;
fluidly connecting a source of flowback water to a backwash filter, filtering said flowback water, separating the fluid output of said flowback water into two flow paths, directing the first flow path to an ozone contact tank and directing the second flow path to a main reactor tank, introducing ozone into said ozone contacting tank whereby the flowback water conveyed by the first flow path is exposed to ozone, conveying the flowback water from the ozone contacting tank to a manifold within said main reactor tank configured to cause hydrodynamic cavitations with said main reactor tank, positioning ultrasonic transducers with said main reactor tanks to create acoustic cavitations within said main reactor tank, conveying the flowback water from said main reactor tank to at least one centrifuge that will separate the solids out of the flowback water.
2. A process for treating flowback water as set forth in claim 1 including the steps of: creating a pressure greater than atmospheric pressure within said main reactor tank.
3. A process for treating flowback water as set forth in claim 1 including the steps of; exposing the flowback water to ultraviolet light after treatment by said at least one centrifuge.
4. A process for treating flowback water as set forth in claim 3 including the step of passing the flowback water through a plurality of media tanks containing activated carbon after exposing the flowback water to ultraviolet light.
5. A process for treating flowback water as set forth in claim 4 including the steps of; passing the flowback water through reverse osmosis pumps and membranes to thereby produce a first output of clean flowback water and a second output of reject water for disposal.
6. A process for treating flowback water as set forth in claim 1 wherein the equipment for performing the process is installed within a standard container that can be moved from one well site to another by truck, rail or ship.
