Case study
500 m³/d Oilfield Produced-Water Oil Removal Project
This project treats oilfield produced water at a scale of 500 m³/d. Gravity settling, dissolved air flotation and PEK tubular membranes are combined to remove oil and suspended solids in preparation for reinjection.
Project overview
This project treats oilfield produced water at a scale of 500 m³/d. Gravity settling, dissolved air flotation and PEK tubular membranes are combined to remove oil and suspended solids in preparation for reinjection.
Plum’s scope of supply
Plum supplied the PEK tubular membrane system for this project. Downstream treatment stages were outside Plum’s scope of supply.
Process route
Gravity settling → dissolved air flotation → PEK tubular membranes
The PEK tubular membrane section follows settling and flotation, providing further oil removal and solid-liquid separation.
