Abstract:
The objective of this study was to investigate the operation parameters in the multistage froth flotation column to the efficiency of motor oil removal from water by multistage froth flotation. Branched alcohol propoxylate sulfate sodium salt with 14-15 carbon number and 4 PO groups (Alfoterra 145-4PO) is also used to form microemulsion with motor oil and as a froth for running the multistage froth flotation column. An increase in surfactant concentration was found to increase the oil removal, whereas the oil removal decreased with increasing air flow rate. An increase in NaCl concentration was found to increase oil removal when NaCl concentration exceed 2%wt removal dramatically decrease. For the effect of feed flow rate, oil removal remained constant.
