High-Capacity Hydraulic Weir Skimmers for Efficient Oil Removal

A weir skimmer is used to remove oil from the water. A weir skimmer has three connected floats supporting a central shallow dish. The top of the dish sits 10mm - 20mm below the surface of the water. Upon starting the skimmer the water in the dish is sucked away by a pump. As the dish empties the surface oil and some water, if the oil is not thicker than 10mm - 20mm, falls into the dish and is pumped to shore. A special floating ring joined to the top of the dish with a rubber skirt that concertinas, will automatically re-adjust the skimming depth to 10mm - 20mm in choppy water. Global weir skimmers range is capacity from 5 tonne/hour to 120 tonne/hour. The larger capacity skimmers (40 tonne/hour +) have hydraulic driven on-board pumps with the smaller skimmers having external suction pumps.
