Abstract: The waste water from the regeneration system of a demineralizer system is treated by ion exchange and filtration so that the water can be immediately reused in subsequent steps of the regeneration process. This reduces the amount of waste requiring further treatment before being released to the environment. The resin used to treat the water can either be exhausted resin from a demineralizer unit or regenerated resin. Some of the acid from the regeneration process may also be recovered for reuse.
