摘要：
A method of reclaiming a formate brine may include increasing the pH of a spent formate brine fluid comprising water-soluble polymers; treating the fluid with an oxidizing agent; and removing at least a portion of suspended solids from the fluid. Further, a method of reclaiming a formate brine may include lowering the pH of the spent formate brine fluid comprising water-soluble polymers; increasing the pH of the spent formate brine fluid to initiate precipitation of materials solubilized in the fluid; treating the fluid with an oxidizing agent to break down remaining water-soluble polymer; and recovering at least a portion of the formate brine.
