Comparison between a Fixed and a Tracking Solar Heating System for a Thermophilic Anaerobic Digester
Emerging and hazardous environmental pollutants like phthalic acid esters (PAEs) are one of the recent concerns worldwide. PAEs are considered to have diverse endocrine disrupting effects on human health. Industrial wastewater has been reported as an important environment with high concentrations of PAEs. In the present study, four short-chain PAEs including diallyl phthalate (DAP), diethyl pht...
Studies on bench scale reactors packed with two different media matrix – Biopac media and Fugino spirals were undertaken to determine the performance at various organic loading rate (OLR) and on one day hydraulic retention time (HRT). Parboiled rice mill wastewater depicted a COD/BOD ratio of 1.6 indicating good degradable nature of the wastewater. Four different organic loadings of 0.8, 1.6, 2...
Avian intestinal spirochaetosis (AIS) is a condition arising from colonization of the caeca and colon of birds with anaerobic spirochaetes of the genus Brchyspira. The purpose of the present study was to evaluate PCR amplification from formalin-fixed, paraffin-embedded tissue method for detecting infected laying hens with Brachyspira pilosicoli with the same primers that have been used for det...
It has been less than two decades since anammox (anaerobic ammonium oxidation) coupled to nitrite reduction has been discovered. Already, this process has been recognized as an important sink for fixed nitrogen in the natural environment and has been implemented as a cost-effective ammonium removal technology. Still, little is known about the molecular mechanism of this remarkable reaction. In ...
Improving anaerobic performance and anaerobic power is the critical aspect on successfully in competitions for many athletes. The purpose of current research was to investigating the effect of various pre-competitions warm-up on anaerobic performance. It has been shown that, differences pre-competitions activity may effect on anaerobic and explosive performance. Effect of general warm-up, witho...
the main theme to conduct present research work was to evaluate the effect of anaerobic granular sludge in degradation of two azo dyes. the study was evaluated in batch experiments where anaerobic and aerobic conditions were integrated by exposing anaerobic granular sludge to oxygen. under these conditions, the azo dyes were reduced, resulting in a temporal accumulation of aromatic amines. subs...
