DEVELOP AN INNOVATIVE LOW LIQUID DISCHARGE SYSTEM

Waste waters : what technology for what purposes ?

Wastewater after pre-deoiling

Reuse Reuse

Ozonation Biofiltration Ultrafiltration Reverse Osmosis

1st stage: Chemical/Biological oxidation Bulk organic matter Micropollutants (PAHs, BTEX) Solids

2nd stage: Ultrafiltration Solids

3rd stage: Reverse osmosis Salt content
