The efficiency of concentration methods used to detect enteric viruses in anaerobically digested sludge
The presence of enteric viruses in biosolids can be underestimated due to the inefficient methods (mainly molecular methods) used to recover the viruses from these matrices. Therefore, the goal of this study was to evaluate the different methods used to recover adenoviruses (AdV), rotavirus species A (RVA), norovirus genogroup II (NoV GII) and the hepatitis A virus (HAV) from biosolid samples a...
متن کاملFermentation of Aerobically Slaughterhouse Sludge for Purposes
Aerobically activated sludge from a pig slaughterhouse wastewater-treatment plant was mixed with 0.35 or 0.5% (wtlwt) dextrose, with 0.5% (wtlwt) dextrose and 0.05 or 0.2% (vlv) f ormic acid, or with 2.5% (wtlwt) molasses and 0.1% (v/v) formic acid, and was pasteurized at 95°C for 5 min. After cooling to approximately 20°C the sludge was inoculated with l@-lo7 cfu Lactobacillus plantarum/g slud...
متن کاملAmmonia Removal from Digested Sludge Supernatant
Wastewater Treatment Plants that make use of anaerobic processes for sludge digestion often have problems with phosphates and ammonia nitrogen “overloads” returned to biological sewage treatment process together with effluents coming from dewatering of digestion sludge. The high concentrations of phosphates and ammonium nitrogen in supernatant constitute 10 – 20 % of entire load brought to biol...
متن کاملRemoval of heavy metals from anaerobically digested sewage sludge by isolated indigenous iron-oxidizing bacteria.
The removal of heavy metals (Cr, Cu, Zn, Ni and Pb) from anaerobically digested sludge from the Yuen Long wastewater treatment plant, Hong Kong, has been studied in a batch system using isolated indigenous iron-oxidizing bacteria. The inoculation of indigenous iron-oxidizing bacteria and the addition of FeSO4 accelerated the solubilization of Cr, Cu, Zn, Ni and Pb from the sludge. pH of the slu...
متن کاملEnteric Bacteria
Biochemical confirmation of salmonellae by conventional tube methods usually requires 2 to 3 days of incubation time preceded by preparation of tubed media and transfer of cultures. The principles of heavy inocula and increased substrate concentrations have been used by Sanders et al. (1) to speed up reaction times and thus reduce the time necessary in the laboratory for analysis. To characteri...
