ABSTRACT:
This invention pertains to a multi-stage separator vessel through which the to-be-cleaned fluid flows. Aeration assemblies within the inner cells disperse micro-fine gas bubbles into the fluid for cleaning purposes. Additionally, the inlet piping contains a separator that begins the separation process before this fluid is discharged into the first cell. An L-shaped passageway interconnects the various flotation cells of this separator with the entrance of each such passageway being at an elevation below its exit. A weir is located within each flotation cell that is adjustable as needed. This weir empties into a channel alongside the separator vessel that collects the separated contaminants flowing over the weir for later disposal.
