    3 Separator Basics 3.1 Separating function Separating function 3.3.1 Bowl The bowl body (10) and bowl hood (2) constituting the bowl casing are held together by the large lock ring (4). In the bowl are the distributor (5) and the disc stack (9) through which the process liquid (oil/water) is passed and where the separation takes place.
  • Page 26 3.1 Separating function 3 Separator Basics Process flow Unseparated oil (201) is fed into the bowl through the inlet pipe and is pumped via the distributor (1) towards the periphery of the bowl. When the oil reaches the holes in the distributor, it rises through the channels formed by the disc stack (2) where it is evenly distributed.

  • Page 27: Clarifier Bowl

    3 Separator Basics 3.1 Separating function Position of interface In a purifier bowl the position of the interface should be located between the disc stack edge and the outer edge of the top disc. The position of the interface is adjusted by altering the pressure balance of the liquid phases oil and water inside the separator.
  • Page 28 3.1 Separating function 3 Separator Basics Process flow The process liquid (201) flows through the distributor (1) to the interspaces between the bowl discs in the disc stack (2). Through the action of the centrifugal force the heavy particles move along the underside of the discs towards the bowl periphery, where they settle on the bowl wall (3).
