ABSTRACT:
A solid-liquid slurry, particularly sugar juice, is flocculated and clarified in an arrangement including a clarifier tank containing therein a mud bed of concentrated removed solids. A preflocculating vessel extends into the top of the clarifier tank and includes upper and lower chambers. The slurry is introduced into the upper chamber to flow turbulently therein, thereby deaerating the slurry. The slurry is transferred from the upper chamber to the lower chamber while the turbulent flow of the slurry is changed to a laminar flow. A flocculating agent, for example a suitable polymer, is introduced into the slurry, such that solids of the slurry coagulate as flocs in the lower chamber. The thus preflocculated slurry is introduced directly into the clarifier tank at a level beneath the surface of the mud bed therein. The liquid of the slurry percolates upwardly through the mud bed and is filtered, thus forming clarified liquid, and the flocs of solids settle downwardly into and form the mud bed. The clarified liquid is removed from the upper portion of the clarifier tank.
