Reuse as reinjection water

the opportunity to produce low-salinity reinjection water for Enhanced Oil Recovery (EOR) processes, thereby yielding the overall oil production volumes.
The technology applied has several advantages as downstream wastewater and upstream injection water are treated in a single process, resulting in major cost reductions. The UF membranes also offer a consistent effluent quality and significantly lower oil, polymer and suspended solids levels, which enables a better performance of the overall system.
