Oil droplets and solid particles removal using circular separator with inclined coalescence mediums : comparison between co-current and counter-current flow

This research investigated the effects of co- and counter-current flow patterns on oil-water-solid separation efficiencies of a circular separator with inclined coalescence mediums. Oil-water-solid separations were tested at different influent concentrations and flowrates. Removal efficiencies incre...
