37 Solutions For each waste type different techniques can be applied : Pretreatment : Excavation and sieving Centrifuging (oil recovery) Hydrocyclone Treatment : Natural / mechanical dewatering Bioremediation Soil washing Stabilization (immobilisation) for further disposal / re-use Thermal Desorption (low & high temperature) Thermal Treatment 37

38 Pretreatment : Excavation / Sieving 38

39 Pretreatment : Centrifuging Liquid Solid separation Oil/Water WWTP Water Oil sludge Decanter Disk Stack Oil Solids Contaminated soil Bioremediation Soil Thermal treatment Immobilisation Disposal + Separation process, volume reduction in various waste fractions - Need for continous and homogeous waste stream Recovery of oil fraction 39

42 Pretreatment : Hydrocyclone Granulometric separation Desilting and desanding 42

43 Treatment : Natural dewatering Oily waste delivery Dewatering of the waste Slow process 43

44 Treatment : Mechanical dewatering Dewatering of the waste Fast process 44

45 Treatment : Bioremediation Reliable for hydrocarbons (short C-chains) + Slow, contamination specific results - Bioremediation 45

46 Treatment : Soil washing Different type and combination of contamination, Save & Robust, re-use recovered fractions + Water consuming - 46

47 Treatment : Stabilisation Reliable for mineral contamination, instant results + Geotechnical application/ re-use - Stabilization of Contaminated Soils & Construction of Landfill 47
