A coalescer is used in series with a hydrocyclone to enhance the removal of a dispersed phase from a continuous phase by first using a coalescer that lacks removal of any separated dispersed phase prior to cyclonic action in the hydrocyclone. The coalescer has no oil outlet and serves to coalesce the droplets or particles of the disperse phase together thereby increasing contaminant size distribution. The second hydrocyclone functions as a separator operating at higher removal efficiency. The method and apparatus are useful to clarify produced water from hydrocarbon recovery operations.
