Inactivation mechanisms of pathogenic bacteria in several matrixes during the composting process in a composting toilet.
This study aimed to compare the inactivation rate and the mechanisms of pathogenic bacteria in three matrixes (sawdust, rice husk and charcoal) during the composting process. The inactivation rate was evaluated with Escherichia coli strain and the damaged parts and/or functions were evaluated with three different media. Normalized inactivation rate constant in three media and from three matrixe...
متن کاملUV inactivation of pathogenic and indicator microorganisms.
Survival was measured as a function of the dose of germicidal UV light for the bacteria Escherichia coli, Salmonella typhi, Shigella sonnei, Streptococcus faecalis, Staphylococcus aureus, and Bacillus subtilis spores, the enteric viruses poliovirus type 1 and simian rotavirus SA11, the cysts of the protozoan Acanthamoeba castellanii, as well as for total coliforms and standard plate count micro...
متن کاملKinetics of inactivation of indicator pathogens during thermophilic anaerobic digestion.
Thermophilic anaerobic sludge digestion is a promising process to divert waste to beneficial use, but an important question is the required temperature and holding time to achieve a given degree of pathogen inactivation. In this study, the kinetics of inactivation of Ascaris suum and vaccine strain poliovirus type 1 (PVS-1), selected as indicators for helminth ova and enteric viruses respective...
متن کاملEffect of Sewage Sludge Solar Drying Technology on Inactivation of Select Indicator Microorganisms
The sanitization effectiveness of sewage sludge solar drying was examined in the aspect of limiting the transmission of pathogenic microorganisms into the environment. The survival rates of indicator bacteria E. coli, faecal streptococci, and rods of Salmonella SenftenbergW775, as well as the eggs of the intestinal parasite Ascaris suum were assessed in dried sludge. The results indicate that t...
متن کاملInactivation mechanism of pathogenic bacteria using lime and ash in composting toilet
A composting toilet, using charcoal and rice husk as matrixes, requires inactivation treatment against pathogenic microorganisms derived from human feces before agricultural reuse. High pH conditions by adding calcium oxide (CaO) and wood ash is effective for lethal inactivation of pathogenic bacteria. However, quantitative information about application is limited. Therefore this study investig...
