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
E4Water, Final Conference, April 19-20 8
ENHANCED DEGRADATION OF ORGANICS
Synergetic combination of ozonation and biofiltration for COD removal (TRL 6)
Biofiltration : 50% Combined ozonation +
