The Coalescing Cone configurations add a set of internal cones to the Natural Clarifier format. These cones direct the flow of dirty water through the cone stack and force free oil to agglomerate into larger drops as the water moves up through the clarifier. These larger drops of oil will separate more readily from the water and float to the top, where it can be skimmed off and separated. The treated water is pulled off below the oil rich surface. Additional cones can be installed for applications where oil concentrations tend to be higher.  4 additional cones can be added to the CLT-300 where 8 additional cones can be added to the CLT-600.  Oil removal can be achieved by using the Belt Mop Skimmer, Funnel skimmer or Oil Skimming Cones
