Abstract: Systems and processes are provided herein for selectively removing zinc from a zinc fluid (14) in order to substantially reduce an amount of zinc waste for disposal in particular settings, such as in an offshore drilling environment. In one embodiment process comprises concentrating a zinc fluid (14) by reverse osmosis (16) and contacting the concentrate (22) with an anionic ion exchange resin (18). In another embodiment process comprises treating a zinc fluid only with an anionic ion exchanger resin. In yet another embodiment the process focuses on multipass treatment with reverse osmosis.
