Chapter 11 Oil Water Separators - Tacoma

The oil separation cell traps and holds oil as it rises from the water column, and it serves as a secondary sediment collection area. The afterbay provides a relatively oil-free cell before the outlet and provides a secondary oil separation area. • The length of the forebay shall be approximately 1/3 to 1/2 the length of the vault. In

Gravity separation : ALS

ALS provides gravity separation, in combination with other techniques, to identify and optimise the process flowsheet for the target mineral. Gravity separation is achieved based on the difference in specific gravity (SG), shape and particle size of the valuable minerals or metals, as compared with the gangue or host rock and the carrying medium.

A node can be removed by using the gravity leave or gravity remove commands. To decommission an active node from the Cluster while on a particular node run gravity leave. If successful, the leave command will output the ID of the initiated removal operation. The operation progress can be monitored using the gravity status command.
