Physical, Chemical and Biological Agents Impacting Disinfection in Residuals

The inactivation of pathogens in residuals can be achieved by exposure to various types of stressors – physical, chemical and biological. The physical stressors include temperature, cavitation and radioactive irradiation (gamma and beta). These processes may solublize the organics, break the cells apart, destroy DNA, and other critical subcellular structures. The most common physical...
