Abstract
A process and system for treating sludge are provided. Sludge is dewatered by introducing pressurized air to the sludge, while the sludge is being moved continuously. The air strips the sludge of its water, thus increasing total solids captured with respect to time. The throughput of the system is therefore also increased. In addition, the pressurized air passing through the sludge support purges contaminants from the pores of the support, thus keeping them clean without the necessity to backwash same.
