Abstract

The present disclosure is directed towards systems and methods for the treatment of wastewater. A system in accordance with one particular embodiment may include a front end system including at least one resin tank configured to contain an ion exchange resin configured to target a particular metal. The at least one resin tank may be configured to receive an output from an oxidation reactor configured to receive a flow of wastewater from a wastewater producing process. The system may further include a central processing system configured to receive a saturated resin tank from the at least one resin tank. The central processing system may further include a vacuum filter band system configured to receive a slurry from the saturated resin tank and to provide a cascading resin rinse to the slurry. The central processing system may further include a repetitive stripping system configured to receive a metal-filled purification unit from a metal specific purification system. The repetitive stripping system may be further configured to sequentially apply the contents of a plurality of acid tanks to the metal-filled purification unit to generate a metal salt. Numerous other embodiments are a…
