Abstract
A clarifier is provided for simultaneously treating a plurality of bodies of liquid-solid suspension in a vertically stacked fashion, with the aim of separating the particulate solids from the liquid, by process steps involving a combination of electrophoresis and reverse osmosis. The clarifier comprises a conical shell which is mounted on a shaft for rotation. The shaft extends through the apex of the shell and is disposed at an upward angle, so that the base of the shell is tilted. A plurality of nested, spaced apart, truncated, conical bands are secured to the inner surface of the shell. The bands each carry an elongate anode electrode on the upper surface and an elongate cathode electrode on the lower surface. Thus there are formed a plurality of vertically stacked, endless, arcuate treatment chambers, with an elongate anode extending along the base and an elongate cathode electrode extending along the top of each chamber. A trough-like container closely surrounds the lower portion of the conical unit, to provide the inner wall for each treatment chamber. The upper portion of the conical unit overhangs the container. In use, fresh suspension is fed into one end of the portion o…
