Research ArticleOpen accessIn the abstractAerobic Biodegradation of Per-Treated Methyl Tert-Butyl Ether By Ozonation in an Up-Flow-Fixed-Bed ReactorM. Sadeghi, M. Arbabi, A. Nikpey, G. MardaniProblem Statement: MTBE is a common pollution of environmental and has become an issue of considerable concern in recent years. It is not readily amenable to remove MTBE by conventional techniques in water treatment. In the present study, the feasibility of the continuous aerobic biodegradation of MTBE, was evaluated in an Up- Flow Fixed Bed Reactor (UFBR). Approach: The UFBR … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,620 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Characteristics of Leachate and Groundwater Pollution at Municipal Solid Waste Landfill of Ibb City, YemenEsmail Al Sabahi, S. Abdul Rahim, W.Y. Wan Zuhairi et al.Problem statement: Yemen one of the developing country suffering from water pollution. Landfill is one of the source of water pollution. There are several boreholes located close to Ibb landfill used for drinking water. A study of composition of landfill leachate and groundwater pollution was conducted at Ibb landfill, which is located at Al-Sahool area, north of Ibb City, Yemen. … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 9,186 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntermittent Aeration in Biological Treatment of WastewaterH. Doan, A. LohiProblem statement: E-coating process is widely used to provide a protective coating layer on metal parts in the automotive and metal finishing industry. The wastewater from the coating process contains organic compounds that are used in the cleaning, pretreatment and coating steps. Organic pollutants can be removed biologically. In the aerobic biological treatment, water aeration accounts for a significant portion … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,131 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Groundwater and Surface Water Pollution at Mitm Area, Ibb City, YemenEsmail A. Sabahi, S. Abdul Rahim, W.Y. Wan Zuhairi et al.Groundwater and surface water samples were collected from Mitm area to study the possible impact of wastewater treatment percolation into the groundwater and surface water. The objective of the study is to assess the groundwater and surface water pollution due to wastewater treatment at Mitm area of Ibb city, in the Republic of Yemen. The concentrations of various physiochemical parameters … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,881 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Microwave and Ultrasonic Pretreatments on Biogas Production from Anaerobic Digestion of Palm Oil Mill EffleuntN. Saifuddin, S A. FazliliProblem Statement: Oil palm production is a major agricultural industry in Malaysia. In 2006, palm oil mills in Malaysia produced more than 58 million tonnes of Palm Oil Mill Effluent (POME). Existing treatment in a series of open lagoons at high ambient temperatures, results in the uncontrolled production of methane and carbon dioxide, which are both green house gases (GHGs). … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,986 accessesView PDFCite
Research ArticleOpen accessIn the abstractTreatment of Wastewater by Natural Lagoon for its Reuse in IrrigationM. Driche, D. Abdessemed, G. NezzalThe process of natural lagoon consists in purifying the waste water by simple flow of the effluent in not very deep ponds where proliferate bacteria, algae and other living organisms, under a surrounding air and in the presence of a solar radiation. For this study, which is spread out over 3 years (2004-2006) and which still continues, we chose the … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,181 accessesView PDFCite
Research ArticleOpen accessIn the abstractTeatment of Work Camp Wastewater Using a Sequencing Batch Reactor Followed by a Sand FilterA. Rezaee, A. Khavanin, M. AnsariWork camps, have to be established quickly, are a transient nature and located in environmentally sensitive areas. Wastewater treatment systems located in the work camps often perform poorly. In response to these deficiencies and the need to provide for reliable, cost effective, high efficiency wastewater treatment, the research team designed a sequence batch reactor (SBR)/ sand filter system that is … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,702 accessesView PDFCite
