Effects of heat, radiation, and thermoradiation on the filterability of sewage sludge
Technical Report
·
OSTI ID:5150468
The effects of heat, radiation and thermoradiation processes on the dewatering properties of raw and primary digested sewage sludges were investigated. These effects were measured by observing the changes in filterability subsequent to treatment. Thermal treatment (40/sup 0/ to 95/sup 0/ C) of the sewage sludge resulted in decreased filterability. Radiation and thermoradiation treatment increased the filterability, the increase being dose and temperature dependent. These treatment methods are not as effective as chemical additives in increasing the filterability of sewage sludge. The combined use of radiation and organic polymer conditioner shows no significant improvement in the filterability of sewage sludge over the use of polymer alone. There appears to be some interaction; however, it shows no useful synergistic effect.
