Abstract
An improved system for dewatering dilute slurries is disclosed. The system includes a spring-loaded sludge feed tray incorporating an adjustable flow splitter plug, along with spring-loaded sludge side guides. The sludge-cake compression section provides for a compression roller which is adjustable between two positions as a component in the backflushing of the sludge carrier screen using cake effluent. Also, a particular screen sludge solids loading range is employed which results in a significant improvement in performance and capacity of the dewatering system.
