Abstract
Generally, the present disclosure provides a process for treating de-oiled oilfield produced water or de-oiled process affected water from hydrocarbon production. In particular, such water is treated with a regenerable polymeric ion exchange resin to remove water soluble ionic surfactants. The treating can involve ion-exchanging ionic polymeric membrane foulants with non-fouling soluble ionic species that can be removed by polymeric membrane.
