Apparatus for retrieving solid material from a separation medium

Abstract From the Canadian patent

A rotating reticulated hydrophobic foam separation medium of one eighth inch thickness or greater and a porosity in excess of forty pores per lineal inch is kept from "plugging" and maintained capable of efficient separation of suspended solids from liquid over a sustained period of time by entraining the solid material from both the foam surface and the reticulated foam structure in outwardly directed fluid flows of various vacuum means. Apparatus to create the entraining flow includes a vacuum nozzle with or without a shroud various couch, roll and vacuum combinations and air or water nozzles, to direct flows through the reticulated structure from within the rotating medium support …
