In a method for improving separation performance of a decanter centrifuge, the centrifuge is inspected to determine whether the centrifuge is operating in a Coriolis-resist or a Coriolis-neutral mode wherein Coriolis forces acting on liquid flow tend to direct the liquid flow radially inwardly or axially, respectively. Upon determining that the centrifuge is operating in a Coriolis-resist or Coriolis-neutral mode, the centrifuge is modified to operate in a Coriolis-assist mode where Coriolis forces act on liquid flow in a radially outward direction and thereby augment the action of centrifugal force in the separations process. Radially extending flow obstructions in a ribbon-type centrifuge are provided with radial vanes to compensate for Coriolis forces and improve centrifuge performance.
A method for improving separation performance of a decanter-type centrifuge wherein liquid flow is in a first direction and solids transport is in a second direction, rotation of the centrifuge generating a radially outward centrifugal force inducing sedimentation of solids out of the liquid flow, the method comprising:
A method for improving separation performance of a decanter centrifuge having bowl and a conveyor and a liquid feed in a middle range of a clarifier pool section of said bowl, said centrifuge being provided with an effluent discharge near one end of said bowl, the method comprising relocating said liquid feed to an end of said bowl opposite said effluent discharge.
