At SkimOil we have developed some better methods and equipment for decanting ash ponds. Our floating weir skimmers (FWS) originally designed as surface oil skimmers, simply drain an area from the top down and remove whatever is flowable on/from the waters surface. In the ash ponds we found that the FWS with their laminar flow-do a great job of removing surface water without stirring up all the stuff under the water surface.
