A PLURALITY OF COUNTERROTATING DRUMS IN SERIES TO REMOVE MATERIALS FLOATING ON WATER AND MATERIALS DISPERSED IMMEDIATELY BELOW THE SURFACE OF THE WATER, A FIRST DRUM PARTIALLY IMMERSED HAVING A SURFACE OF ORGANOPHILIC MATERIAL, THE DRUM ROTATING IN THE DIRECTION OF FLOW OF THE WATER REMOVES HEAVY VISCOUS CONTAMINANT MATERIALS. ANOTHER DRUM IMMERSED MORE DEEPLY AND LOCATED DOWNSTREAM FROM THE FIRST DRUM HAS A HYDROPHILIC SURFACE MATERIAL AND THE DRUM ROTATES AGAINST THE FLOW OF WATER TO REMOVE LIGHT OILY CONTAMINANT MATERIAL. SCRAPER MEANS CLEAN THE CONTAMINANTS FROM THE SURFACES OF THE DRUMS AND CONTAMINANT REMOVAL MEANS REMOVE THE CONTAMINANTS FROM THE SYSTEM.
