“…Indeed, the enumeration is carried out by (Tchobanoglous et al, 2003;James et al, 2008a): (1) direct microscopic count, (2) colony forming units (cfu), with culture in solid medium, and (3) the most probable number (MPN) method as a statistical determination. According to: (1) the relative difficulty of the process preparing, (2) the costly method, and (3) time consuming (Tchobanoglous et al, 2003;Joret et al, 1980), only a few data on Rotavirus (Bosch et al, 1986) and Adenovirus (Williams and Hurst, 1988) are available. A few data of presence/absence of Enterovirus, Adenovirus and Hepatitis A viruses (Vantarakis and Papapetropoulou, 1988) are also available.…”

The sewage sludge from wastewater treatment plant is a potential source of infectious organism. The number and type of pathogens in sludge depends on various factors namely, the wastewater source, the type of treatment plant, and other environmental factors such as the biological medium offered by the sewage sludge. The principal sludgeborne diseases are presented followed by discussion on biological aspect of growth and occurrence. The overall objective of this work is to estimate kinetic reduction of pathogen population in sludge during different thermaldrying process including: the agitated conductive drying, drum drying, solar drying, and fry-drying. The temperature curves were reported from literature except frying data which were determined in experiment. In order to apply the temperature influence on pathogens population, kinetic parameters for the thermal inactivation (D, z-values) were chosen from literature. Values of concentrations of each pathogen were also extracted from scientific review of pathogens in bio-solids. This study conducted to resolve the survival kinetic of Hepatitis A viruses. The result showed that a concentration of 7 × 10 4 cfu/100 ml initially present in the sewage sludge is significantly reduced during the heat drying processes except the solar plant. The sewage sludge is completely disinfected when heated for 20 min, 10 min, and 10 s, respectively, during the agitated conductive process, vacuum fry-drying, and drum drying process.

“…For low sample volumes (< 100 l) the method produces a low eluate volume which does not need secondary concentration prior to inoculation into cell culture. However, in common with the performance for glass®bre tube ®lters, the recovery varies widely with the type of sample, from 60% with potable water to 20% with urban wastewater (Joret et al 1980). Bosch et al (1988), using glass powder to concentrate rotavirus from natural and seeded tap water and sewage, obtained approximately 50% recovery from the tap water but only 5% from sewage in seeded samples, though, however, 100% of unseeded sewage samples were positive for rotavirus.…”
