A Newly Developed Solid Liquid Separation Bath for Settling and Floating Solid Matter

Abstract

A new type of bath for use in separating settling and floating solid matter from liquid has been developed.
In its operation, a liquid containing solid matter flows in a tangential direction into the round bath and the liquid freed of solid matter flows out of the outlet port located on the lateral wall. Liquid containing a high concentration of floating solid flows out of the overflow pipe located at the bath center, while liquid containing a high concentration of settling solid flows out of the drain port in the bottom of the bath.
Experiments show that the separation and discharge functions of the new separation bath are better than those of the swirl concentrator. It was confirmed that the efficiency of separation was primarily determined by the nondimensional parameter h_c'/h₀. The approximate equations of separation efficiency were obtained.
