ABSTRACT:
System for separating solids from slurry containing a separable solid in a liquid carrier, such as an industrial waste. The slurry is flowed into a separation chamber positioned over a slower moving foraminous medium to effect cross-flow separation of liquid from the slurry in an initial stage and followed by separation of solids from the slurry in a second stage all the separation being effected employing a single forwardly moving filtration medium. The flow rate of liquid, the rate of travel of the foraminous medium, and the differential pressure across the foraminous medium, as established by the pressure exerted by the flowing liquid on the foraminous medium and the relative pressure underneath the foraminous medium, are controlled at different locations along the length of the separation chamber to provide optimum steady-state separation for a given waste stream.
