Abstract:
1. A method for separating batches of solid material from a liquid slurry including biologically hazardous material and for sterilizing separated solid material, said method comprising the steps of: introducing said slurry into a chamber of a pressure vessel having a filter or a screen extending thereinto and being in fluid communication with a first main valved outlet port of said chamber, for separating solid material in said slurry from liquid in said slurry; allowing liquid in said slurry to pass through said filter or screen and be discharged from said chamber; fluidly isolating said chamber from a surrounding environment after said liquid has been discharged from said chamber; after fluidly isolating said chamber, injecting steam into said chamber wherein said steam contacts said solid material remaining in said chamber to heat said solid material to a predetermined sterilization temperature and conveying a condensate out of said chamber; maintaining said predetermined sterilization temperature for a predetermined period of time; and removing sterilized solid material from said chamber.
