Abstract:
A continuous flow sludge pasteurization system, comprising:a liquid flow chamber having an inlet and an outlet and defining a continuous liquid flow path for maintaining a continuous flow of a slurry from said inlet toward said outlet at a predetermined rate for establishing a minimum period of residence time of the slurry within said flow chamber sufficient to kill all pathogens in said slurry at a predetermined minimum temperature of between about 145 and 160 degrees F;means for introducing a continuous flow of a liquid slurry of sludge into said liquid flow chamber and for establishing and maintaining a continuous flow of a liquid slurry through said liquid flow chamber from said inlet to said outlet at said predetermined rate; andmeans for introducing heat into a liquid slurry being introduced into said liquid flow chamber for heating said continuous flow of slurry to said predetermined minimum temperature.
