Moisture effects on inactivation and growth of bacteria and fungi in sludges
Abstract
The sewage sludge irradiation program at Sandia Laboratories has included treatment of liquid and solid sludges. Considerable data on liquid sludges, raw as well as digested, have been generated. For studies of the value of sludge as a cattle feed supplement, however, we have irradiated dried raw and dried digested sludges. In addition, a significant portion of our recent efforts has dealt with pathogen reduction in composted sludge. Our primary research goal is the determination of parameters for inactivation of pathogens by ionizing radiation and/or heat. The effects of reduced moisture levels on these rate parameters may be important. This paper presents very recent data in this area for bacteria and fungi. The results of experiments on growth (and the inhibition of growth) of bacteria and fungi in composted sludge, a low-moisture system, are also presented.
