Across the nation, food service establishments using onsite wastewater treatment systems often experience pretreatment system and/or drain field performance problems. This study used statistical analysis of restaurant management practice and primary cuisine type to observe their influence on five-day biochemical oxygen demand (BOD5), total fats, oils, and greases (FOG), total suspended solids (...

recently, hardware sensors are widely used in monitoring and measurement of water quality parameters. constraint of the instrument to measure some water quality parameters such as the 5-day biochemical oxygen demand (bod5), which are time consuming, causes efforts are diverted to the use of software sensors for online prediction of bod5. the main goal of this research is developing an appropria...

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...

Many of the current strategies for removing pollutants from water are based on nanomaterials and nanotechnology. Lower values Biological Oxygen Demand (BOD5) Chemical (COD) in results reduction amount oxidizable pollutants. We present a study COD BOD5 Wadi El Bey River (Tunisia), using magnetite nanoparticles (MNPs) magnetic fields. The removal reached higher than 50% after 60 min, with optimum...

Understanding the characteristics of non-point sources (NPS) pollutions can provide theoretical support for improving water quality. Siheshui watershed located in south China was selected to explore the characteristics of NPS pollutions in rainfall-runoff process. In this small agricultural watershed, five flood events and one non-flood event were monitored, and the water quantity and quality c...

The objective of this study was to identify the organic compounds removed from the leachates when treated with coagulation-flocculation and Fenton-Adsorption by gas chromatography coupled to mass spectrometry (GC-MS) in order to identify toxic compounds that could be harmful for the environment or human health. Physico-chemical characterization of the raw leachates (RL) was carried out before a...

Characterization and evaluation of a biological submerged filter was carried out on a full-scale pilot plant performing removal of biochemical oxygen demand (BOD) and total nitrogen (TN) from pre-treated urban wastewater. The average influent values of BOD5, chemical oxygen demand (COD) and TN were 370, 1,015 and 60 mg/L, respectively. The pilot plant produced good discharge quality during stea...
