Research ArticleOpen accessIn the abstractUnconventional Approach for Demineralization of Deproteinized Crustacean Shells for Chitin ProductionN.S. Mahmoud, A.E. Ghaly, F. ArabChitin is a versatile environmentally friendly modern material. It has a wide range of applications in areas such as water treatment, pulp and paper, biomedical devices and therapies, cosmetics, membrane technology and biotechnology and food applications. Crustacean waste is the most important chitin source for commercial use. Demineralization is an important step in the chitin purification process from crustacean waste. … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 1 · 31 Mar 2007 · 8,799 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordRemoval of Coliform Content in Sewage Treatment Plant Using a Sand Filtration System with Potassium Permanganate PowderSona Pazdar, Saeid Eslamian, Seyedeh Zahra Hosseini-Teshnizi et al.Reuse of refined sewage with two goals of providing more water and protecting the environment from pollution is one of the solutions to water supply problems and one of the potential sources for irrigation in agriculture. The aim of this study is to evaluate the possibility of effluent disinfection using a sand filtration system to reduce microbial contamination with potassium … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 27 Jun 2019 · 7,583 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordApplication of Moving Bed Biofilm Process for Biological Organics and Nutrients Removal from Municipal WastewaterM. Kermani, B. Bina, H. Movahedian et al.In this study, experiments have been conducted to evaluate the organics and nutrients removal from synthetic wastewater by a laboratory scale moving bed biofilm process. For nutrients removal, moving bed biofilm process has been applied in series with anaerobic, anoxic and aerobic units in four separate reactors. Moving bed biofilm reactors were operated continuously at different loading rates of nitrogen … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 9,092 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordModelisation of Nitrification under Inhibited Environment by Moving Bed Bio-Film Reactor TechniquePham Thi Hong Duc, Le Van Cat, Jean-Luc VaselProblem statement: Nitrification by Moving Bed Biofilm Reactor (MBBR) involves physical, chemical and biological processes to remove toxic ammonia for aquaculture that are governed by a variety of parameters, like substrate and dissolved oxygen concentrations, organic matters, temperature, pH, alkalinity and turbulence level, which impact negatively or positively on nitrification kinetics. Approach: The situation becomes more serious as the reaction … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 6,946 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordNumerical Modeling of Flow in a Horizontal Sand FilterRuth Mossad, Hal AralProblem statement: Horizontal sand filters may offer some advantage over vertical sand filters as they could be used for in-line treatment of wastewaters. Horizontal pipelines of tens and if not hundreds of meters length, filled with ordinary sand or permeable reactive media such as activated carbon or natural zeolite or iron filings, may be used to remove impurities from mine … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,502 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDecolorization of Remazol Brilliant Blue Dye Effluent by Advanced Photo Oxidation Process (H2O2/UV system)A. S. Mahmoud, M. S. Brooks, A E. GhalyAdvanced photo oxidation processes hold great promise for the improved treatment of textile dye effluent. In this study, the effectiveness of a H2O2/UV system for the decolorization of remazol brilliant blue effluent was investigated by examining the optimum conditions for dye removal in two reactors (coil and conventional). The results showed that the coil reactor had a higher temperature profile … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 8,007 accessesView PDF Cite
