Abanaki Model 4抓地机是从水和水碱溶液中去除油的一种可靠而有效的手段。通常,脱脂物本身会将油降低到可接受的水纯度水平。根据液体的特性,仅Model 4仅将油含量降低到少于每百万的水中少于五分之一。该单元在过滤前可以用作预处理,并与合并系统一起使用。型号4皮带油撇渣器利用连续皮带和雨刮器从流体表面卸下多达20加仑的油。该皮带在电动机和滑轮系统上运行,穿过受污染的液体从表面捡起油。穿过头轮皮带轮后,皮带穿过串联的雨刷刀片,在那里油被刮掉皮带的两侧并排出。尾滑轮具有法兰,可以使其在皮带内部自由滚动而不会被移开。它不需要轴承,也不需要固定在水箱上。如果存在湍流条件,则可选的系绳和笼子组件可防止尾滑轮被移开。 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.
