| Résumé | Liquid phase agglomeration techniques developed at the National Research Council of Canada have been applied for the recovery of organic material from the fine tails produced by surface mining, bitumen extraction plants. The fractions separated by these techniques include residual bitumen and naphtha plus solids associated with strongly adsorbed largely insoluble organic matter. After separation of these hydrophobic components, the cleaned sludge has been found to show altered settling behaviour. The present study is a continuation of our previous investigation on the settling behaviour of cleaned sludge after the removal of organic components using oil phase agglomeration techniques. In general the sludge separated into three layers: relatively clean water on top followed consecutively by a suspension of colloidal solids and a clean compacted solids layer. Dewatering of the suspension fraction, containing colloidal solids, was also investigated using conventional coagulation/flocculation techniques. The results of this investigation suggest that up to 60 w/w% of the total water in the sludge can be recovered for recycling. Overall water recovery depends upon the selected levels for the variables in the oil phase agglomeration technique. |
