  • Process for removing interstitial water from a wastewater sludge
    Publication number: 20050109713
    Abstract: A process for removing water from sludge has the steps of passing the sludge through a chamber, injecting carbon dioxide gas under pressure into the chamber as the sludge passes through the chamber, and flashing the carbon dioxide-injected sludge through an orifice into a vessel so as to release carbon dioxide gas from the sludge. The flashed sludge is returned to a digester or is dewatered to remove water from the sludge. The carbon dioxide gas is injected at no less than 14.7 p.s.i.a. of pressure.
