Abstract
Abstract In a system for separating a clear liquid phase from a combined liquid and solid phase mixture in a sedimentation container wherein the mixture is caused to pass upwardly through a bundle of parallel inclined tubes within which the settling of the solid phaseout of the liquid phase is completed with the clear liquid phase passing out of the top of the tubes into a collecting vessel from which the clear liquid is then drained, the improvement comprising floating said bundle of inclined tubes within the liquid mixture so that the clear liquid phase may be removed from the system at a steady uniform rate despite changes in the liquid level in the sedimentation container.

A process for separating a liquid phase from solid phase dispersing therein, which comprises the steps of a. introducing a combined liquid and solid phase mixture into a container, b. floating a bundle of parallel open-ended tubes at an inclined angle in the liquid contents of said container so that the top of the tubes is maintained in a position below the liquid level in the container, the top of said tubes being inclosed within a liquidtight vessel, whereby the liquid in the container is caused to flow through the tubes at a velocity which will permit the solid contents to settle against the walls of the tubes, and c. draining the clear liquid phase that Passes out of the top of said tubes into said vessel from said vessel to the exterior of said container.
