Maximum wood extractive removal was achieved by flotation with the addition of 80 mg/L of the cationic surfactant dodecyltrimethylammonium bromide (DoTAB) at pH 5.0 and 60 șC for 20 min with an air flow of 4.5 L/min and impeller speed of 1300 rpm. Under these conditions the removal efficiency of total extractives was close to 95%. Process water treated in this way would be suitable for recirculation in a pulp or paper mill and would result in significant reduction in problems caused by accumulation of wood extractives.
