Oil producers often inject water into subterranean reservoirs to keep the pressure up and extract as much oil as possible. The injection water has to meet high standards to optimize oil recovery.
The three main sources for water injection are seawater (offshore), river/lake/well water (onshore) and produced water (on- and offshore).
The dead-end operation mode, with a small footprint and low energy consumption, is very suitable for (sea)water applications in which the feed has an oil content of less than 5 mg/ltr, and TSS of less than 30-50 mg/ltr.
Crossflow operation concentrates the oil fraction 10 to 20 times and needs little chemical cleaning compared to conventional systems. It is better suited for much higher TSS concentrations (<200 mg/ltr), combined with an oil content of less than 1000 mg/ltr.
