The increase in column height subtly affected the mixing process, by influencing the transition from plug-flow-like to mixed flow conditions. The backflow was calculated in all cases as approximately 10% of the net incoming liquid flow, and 4 to 14 perfectly mixed cells were found to represent the collection zone liquid-phase RTDs, with the higher number of cells corresponding to high liquid and low gas flowrates. Vertical baffles were found to enhance rather than attenuate the collection zone mixing

Three colours were used for the experiments: Basic Yellow 28 (acidic), Direct Black 22 (basic) and Disperse Orange 30 (dispersion colour). All three were effectively removed by flotation within 15 to 30 min. Sodium lauryl sulfate and dodecylamine were found to be effective as collectors in the removal of colour, which was also found to be related to the pH of the solution and the amount of collector added to it, with high collector dosages causing the process to become pH‐independent.
