More Information www.agilent.com/chem/icpms Introduction Biogas is the term used to describe the mixture of methane, carbon dioxide, nitrogen and other components resulting from the anaerobic fermentation of a variety of biodegradable materials including animal waste, domestic sewage sludge and municipal landfill waste. Because of its methane content (40-75%), biogas can be used as a substitute...
The data on the occurrence of keratinolytic fungi in sewage, municipal solid waste and waste-contaminated habitats are reviewed. In these habitats, keratinolytic fungi occur with extreme abundance. The factors influencing qualitative and quantitative compositions of the fungi in the habitats are discussed. It is concluded that keratinolytic fungi can be the bioindicators of environmental pollut...
BACKGROUND & OBJECTIVE Availability of clean water and adequate sanitation facilities are of prime importance for limiting diarrhoeal diseases. We examined the water and sanitation facilities of a village in southern India using geographic information system (GIS) tools. METHODS Places of residence, water storage and distribution, sewage and places where people in the village defaecated were ...
Urban development is rapidly expanding across the globe and is a major driver of environmental change. It is important to understand how bird species responds to urbanization. Therefore I conducted a qualitative study of birds associated with waste sites such as dumpsite and sewage stabilization ponds was carried out on Moshi municipal. The study assessed the diversity between dumpsite and sewa...
Current mainstream technologies for wastewater treatment, such as activated sludge and tertiary nutrient removal are too costly to provide a satisfactory solution for the increasing wastewater problems in developing regions. Besides, these technologies do not allow for re-use of valuable energy and nutrients contained in the wastewater. This paper introduces a so called ‘Cleaner Production’ con...
Background and Objective: Increased untreated wastewater and unsustainable development of agriculture has deteriorated water quality of rivers. The aim of this study was to determine the quality of water in Gorganrud River basin using NSFWQI IRWQISC and Liou Pollution Index and compare them with the global standards. To do this, GIS software.was used Materials and Methods: In this study, 5 sam...
Human-specific Bacteroides HF183 (HS-HF183), human-specific Enterococci faecium esp (HS-esp), human-specific adenoviruses (HS-AVs) and human-specific polyomaviruses (HS-PVs) assays were evaluated in freshwater, seawater and distilled water to detect fresh sewage. The sewage spiked water samples were also tested for the concentrations of traditional fecal indicators (i.e., Escherichia coli, ente...
wheat flour is known as the best nutrients supplier for human. in this research, the effects of combined application of nitrogen fertilizer, farmyard manure (fym), sewage sludge and municipal waste compost on nutrients concentrations of wheat flour (triticum aestivum cv. alvand) were studied in a randomized complete blocks design with 15 treatments and three replicates in agricultural research ...
Preface The purpose of this publication is to describe on-site technologies for treating domestic sewage where conventional means (public sewer or septic tank with drainfield) are not available. These technologies are described as alternatives in this publication. Our goal is to provide information that can be used by property owners and residents to initiate action to rectify sewage disposal p...
