Case study
1,200 m³/d Oilfield Produced-Water Tubular Membrane Project
This 1,200 m³/d project treats oilfield produced water using dissolved-air flotation and PEK tubular membranes. The process separates oil and suspended solids before the subsequent reinjection-water treatment duty.

Project overview
This 1,200 m³/d project treats oilfield produced water using dissolved-air flotation and PEK tubular membranes. The process separates oil and suspended solids before the subsequent reinjection-water treatment duty.
Process route
Dissolved-air flotation → PEK tubular membrane oil and suspended-solids separation
Process roles
Flotation provides upstream oil and solids separation, followed by tubular membranes for further retention of separable oil droplets and particles. The case focuses on this flotation and tubular-membrane treatment route.
