Abanaki 4型捕油器是一种可靠和有效的从水和水基溶液中去除油的方法。通常,浮油本身会将浮油降低到可接受的水纯度水平。根据液体的特性,仅Model 4就有可能将水中的含油量降低到百万分之五以下。该装置可用于过滤前的预处理,并与聚结系统联合使用。4型带式除油器采用连续的皮带和刮油器,每小时可从流体表面去除20加仑的油。在马达和皮带轮系统上运行的传动带穿过被污染的液体,从表面取油。皮带通过头部滑轮后,通过串联式刮油叶片,刮去皮带两侧的油排出。尾部滑轮有法兰,允许它在皮带内部自由滚动而不被移动。它不需要轴承,也不需要固定在油箱上。如果湍流条件存在,可选的系绳和笼总成防止尾滑轮被移动。 Oil skimming makes use of the differences in specific gravity and surface tension between oil and water. These physical characteristics allow the belt to attract oil and other hydrocarbon liquids from the surface of the fluid. The Model 4 can be used in tanks with depths as shallow as one foot, or as deep as 100 feet.
