Challenge
- Unpredictable (toxic) inlet composition
- Fluctuating compositions
- DRIRE regulations including BoD < 300 ppm for discharge to sea
- Limited space to combine MPPE with 2 biorotors
Performance BOD: 2300 to < 300
MPPE removes:
- Aromatics (50 ppm)
- Chloroform/Dichloromethane (1300 ppm)
- AOX (360 ppm)
Biorotors removes:
- Remaining AOX
- Remaining (non toxic) BOD/IOD

The MPPE process
MPPE stands for Macro Porous Polymer Extraction. Polymer beads contain a specific immobilized extraction liquid. Hydrocarbon contaminated water is passed through a column packed with MPPE particles. The hydrocarbons are extracted from the water at any designed efficiency up to 99.999%. The MPPE particles can simply be regenerated by heating with steam. The removed hydrocarbons are recovered as an almost 100% pure product. No other waste stream is created. No chemicals requires, no off gasses produced.
