CPI Oil Separator equipped with Multi-Stage Oil Separator (MuSOS) technology, utilizes a three-layer media system to separate sludge, oil, and water.

Oil and water naturally separate due to differences in specific gravity. However, smaller oil droplets are more difficult to separate because they are carried by the flow and have minimal buoyant force. With the use of specialized media, these fine oil particles are captured, allowing them to coalesce and form larger droplets with sufficient buoyancy to rise and separate efficiently. These three layers consist of:
