Anaerobic digestion has been proven as sustainable process technology for organic waste conversion into renewable bio-energy. This study was conducted to evaluate the performance of mono-digestion different types food substrates using pilot scale anaerobic bio-digester (1200 L) in terms biogas production and chemical oxygen demand (COD) removal efficiency. The biochemical methane potential (BMP...

background: to determine prospectively the prevalence of anaerobic and aerobic infection in early onset (during 72 hours of age) neonatal sepsis, in tehran vali-e-asr hospital. methods: among all the live birth, neonates suspecting of having septicemia were investigated for isolation of micro­organisms. culture bottle containing enriched tryptic soy broth was used for standard blood culture sys...

High organic strength waste such as wastewater generated from various industrial activities and sludge generated from industrial and municipal wastewater treatment plant require treatment prior to disposal in order to reduce environment pollution load and also to comply with disposal norms. Waste containing organic impurities in nature must be treated biologically using life forms such as micro...

The maximal accumulated oxygen deficit (MAOD) method has been extensively, but unfortunately not very methodically, used; the procedure used to determine the MAOD varies considerably. Therefore, this review evaluates the effect of different numbers and durations of submaximal exercise bouts on the linear power output (PO)-oxygen uptake ((.)VO2) relationship and thus the MAOD. Changing the numbe...

in this paper, startup performance of upflow anaerobic hybrid reactor and upflow anaerobic sludge blanket reactors in anaerobic treatment of distillery spentwash has been studied under identical conditions of operation. various effluent characteristics like ph, electrical conductivity, chemical oxygen demand, biochemical oxygen demand and total solids and other process parameters like biogas p...

Studies of anaerobic interval training can be divided into 2 categories. The first category (the older studies) examined interval training at a fixed work-rate. They measured the time limit or the number of repetitions the individual was able to sustain for different pause durations. The intensities used in these studies were not maximal but were at about 130 to 160% of maximal oxygen uptake (V...

Microbial populations associated with methanogenic fixed- or floating-bed bioreactors used for anaerobic digestion of lignocellulosic waste were investigated. Fluorescent in situ hybridization (FISH) was used to characterize microorganisms in samples obtained from different heights in the reactors, which were operated in a semi-continuous manner (feeding and mixing once every 2 days). The FISH ...

The design and operation of wastewater treatment systems for hospital is a challenge for wastewater engineers. In this study, a pilot-scale system integrated anaerobic-aerobic fixed film reactor for hospital wastewater treatment was constructed and its performance was evaluated. The aim of the study was the elimination of organic compounds and a significant reduction of bacteria. The system had...

After immobilization of anaerobes on polyurethane foam in a thermophilic, fixed-bed, anaerobic digester supplied with acetate, the results of real-time PCR analysis indicated that the major immobilized methanogenic archaea were Methanosarcina spp., and that the major free-living methanogenic archaea were Methanosarcina and Methanobacterium spp. 16S rRNA gene densities of Methanosarcina spp. and...
