Decantation is a process of separation of two immiscible liquids having different densities.  When these liquids allowed to settle forms two distinct layers, heavier at bottom and lighter at top.  Goel has developed a Decantor which is suitable for continuous decantation.
The mixture of liquids is continuously fed in the Decantor at low velocity.  This allow sufficient residence time for the formation of separate layers.  The light phase liquid is continuously removed from the light phase outlet at the top.  The heavy phase liquid enters the dip pipe at lower end and overflow in the discharge pipe and is removed from the bottom.

Goel's Decantor provides continuous separation, visual monitoring, and ensure separation even after feed is stopped.

Decantors can be provided with adjustable overflow valve, (Type B) to adjust the position of interface for different operating situations.
