Research ArticleOpen accessIn the abstractHospital Wastewater Treatment Using an Integrated Anaerobic Aerobic Fixed Film BioreactorA. Rezaee, M. Ansari, A. Khavanin et al.The design and operation of wastewater treatment systems for hospital is a challenge for wastewater engineers. In this study, a pilot-scale system integrated anaerobic-aerobic fixed film reactor for hospital wastewater treatment was constructed and its performance was evaluated. The aim of the study was the elimination of organic compounds and a significant reduction of bacteria. The system had been operated … …American Journal of Environmental Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 8,147 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Chemical Admixtures on the Engineering Properties of Tropical Peat SoilsBujang B.K. Huat, Thamer A. Mohamed, Shukri MaailThis research describes a study on the effect of chemical (cement and lime) admixtures on the index and engineering properties (compaction and unconfined strength) of tropical peat soils. The ordinary Portland cement and hydrated lime were used. The amounts cement and lime added to the peat soil sample, as a percentage of the dry soil mass was in the range … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 8,472 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Performance of the Milling Process Of Malaysian Palm Oil Using The Life Cycle Assessment ApproachVijaya Subramaniam, Ma An Ngan, Choo Yuen May, Nik Meriam Nik SulaimanMalaysia is currently the world leader in the production and export of palm oil. This study has a gate to gate system boundary. The inventory data collection starts at the oil palm fresh fruit bunch hoppers when the fresh fruit bunch is received at the mill up till the production of the crude palm oil in the storage tanks at … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 8,819 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiomedicine and Informatics Model of Alzheimer's DiseaseKang Cheng, Chang-Hua ZouIn a perspective of biomedicine and informatics, the mechanism of Alzheimer's, senile amnesia, or other aging-associated and cognitive impairment related diseases involve four important informative processing procedures: propagation, consolidation, retrieval and cognition, In this study, we systematically model the four procedures based on published experimental data. When modeling the propagation, we develop an equivalent circuit of biological membrane to describe … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 28 May 2007 · 6,824 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacteristics of Nitrogen Removal from Old Landfill Leachate by Sequencing Batch Biofilm ReactorLong Tengrui, Anas F. Al-Harbawi, Lin Ming Bo et al.Municipal landfill leachate is a high strength wastewater characterized by high concentrations of organics and ammonia and potentially containing toxic materials. The paper reports the results of a laboratory scale investigation aimed at evaluating the effectiveness of mature municipal landfill leachate treatment by a biological stage (used SBBR as a biological treatment) to study the nitrogen removal capabilities for treatment … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 8,039 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling of Wastewater Oxidation under Microgravity ConditionsBoyun Guo, Donald W. Holder, David S. SchechterVolatile removal assembly (VRA) is a module installed in the International Space Station for removing contaminants (volatile organics) in the wastewater produced by the crew. The VRA contains a slim pack bed reactor to perform catalyst oxidation of the wastewater at elevated pressure and temperature under microgravity conditions. Optimal design of the reactor requires a thorough understanding about how the … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,888 accessesView PDFCite
