Abstract
A 3-phase centrifugal decanter separates a mixture of a light liquid phase, a heavy liquid phase, and solids. The decanter employs two types of dam holders, each carrying a substantially similar dam capable of passing either liquid phase therethrough depending upon the type holder carrying the dam. By mounting the holders with their dams to prepositioned openings provided in a front-located hub, both liquid phases are caused to be discharged through the hub to specified compartments. The two types of holders are capable of being mounted interchangeably to the hub openings. Dams are interchangeable in the holders. By interchanging the positions of the holders, each liquid phase may now be directed to the other's compartment. The holder carrying the dam for discharging heavy liquid phase cooperates with an underdam which prevents light liquid phase from passing through or therearound.
