The CPI consist of a number of inclined corrugated plates mounted parallel to each other at spacing. The raw water containing the oil and suspended solids passes between the plates from top. Laminar flow conditions are essential for the effective gravity separation of the water, the oil and suspended contaminants. In the course of passing from pack inlet to pack outlet, the oil floats upwards into the tops of the corrugations and rises up the incline of the plate to the surface of the system where it is removed by a skimmer. The sludge moves towards the bottom of the corrugations and slides down the incline of the plate spacing. From there the sludge is collected in a hopper to be discharged intermittently through a blow off valve manually or settled sludge cannot recontaminate the treated water.
THE PRINCIPLE OF GRAVITY SEPERATION
Separation by gravity utilizes the density difference between oil and water. Oil Globule in water will attain a constant rising velocity when the resistance to motion Caused by the water is equal to the rising force created by the density difference.
