Abstract
A system is provided for treating contaminated water. The system includes a bioreactor having an outlet for treated water and a filter coupled to receive treated water from the outlet of the bioreactor. The filter is configured to operate in an anoxic mode. The filter has: (a) a vessel configured to receive the treated water, (b) a membrane associated with the vessel and positioned to extract permeate from the received water, (c) a fluid outlet positioned to direct fluid toward the membrane to inhibit film build up on the membrane, (d) a fluid recirculator positioned to recirculate fluid between the vessel and the fluid outlet, and (e) an oxidant supply positioned to introduce an oxidant into the vessel, the oxidant supply being adjustable to control the oxidation-reduction potential of the received water in the vessel within a predetermined range.
