Produced water (PW) is ,wastewater, generated from oil exploration, and requires treating for oil and suspended solids removal. The viability of an effluent treatment unit process for this duty depends both on its efficacy, in terms of oil removal and, for offshore applications esp., its size, in terms of its area (FA, m/h) and vol. (FV, 1/h) footprint per unit vol. flow.
