This paper reports the results of two sewage treatment tests in a community of 15,000 inhabitants. The sewage treatment plant is subject to strong fluctuations in load (BOD5, COD, TKN), and in particular in the BOD5/TKN ratio. These fluctuations adversely affect the biological denitrification, as demonstrated by many pilot and real-scale plants. The plants we tested were subjected to two treatm...
Seghezzo, L. (2004), Anaerobic treatment of domestic wastewater in subtropical regions, Ph.D. thesis, Wageningen University, Wageningen, the Netherlands. In this thesis, the use of upflow anaerobic sludge bed (UASB) reactors for sewage treatment was studied in the city of Salta, northwestern Argentina. The climate in this region can be defined as subtropical with a dry season. Mean ambient temp...
Wastewater consists of a complex mixture of substances. During wastewater treatment these harmful substances can be eliminated or degraded. However, persistent compounds released with the treated sewage effluents enter the environment and pose a risk to animal and human life. To determine the potential risks involved, screening tests are needed to monitor wastewater for potential toxic contamin...
background methicillin-resistant staphylococcus aureus (mrsa) is known as a common pathogen in nosocomial and community-acquired infections. sewage acts as an environmental reservoir and may have a significant role in development and dissemination of antibiotic resistance. objectives this study was undertaken to determine the epidemiological relatedness between the mrsa isolated from sewage and...
In this study, the precipitation effects because of weather variations and receiving water volumes collected by sewage treatment plants were examined to obtain knowledge required for improving construction ideal located in cool climates. The quantity data acquired from Meteorological Society Japan Mombetsu Aqua Center, respectively. results showed a positive correlation between amount reaching ...
This study aims to evaluate the performance of sewage treatment plant in Al-Diwaniya, one cities southern part Iraq. evaluation could be used facilitate effluent quality assessment or optimal process control plant. The influent reaching is considered a medium strong strength with BOD5/COD ratio range 0.23 and 0.69 which can an easily degradable by biological processes performed activated sludge...
