Abstract
A treatment system is provided and comprises a precipitation unit and a recovery unit. The precipitation unit is configured to treat a solution using one or more miscible organic solvents to produce a mixture of precipitate solids and a liquid. The recovery unit is in fluid communication with the precipitation unit and configured to facilitate separating the liquid at least into an organic phase liquid and an aqueous phase liquid comprising a portion of the one or more miscible organic solvents. The treatment system further comprises a purification unit comprising one or more membrane devices in fluid communication with the recovery unit and configured to separate at least a portion of the one or more miscible organic solvents in the aqueous phase liquid from the aqueous phase liquid. A treatment system and a treatment process are also presented.
