Research ArticleOpen accessIn the abstractApplication of Gamma irradiation in treatment of Waste Activated Sludge to Obtain Class a BiosolidsMohammed I. AL-Ghonaiem, Abdelnasser Salah Shebl Ibrahim, Ali Abdullah Al-SalamahProblem statement: The main objective of the current study was investigation of the possible application of Gamma irradiation for treatment of the activated sludge generated wastewater treatment stations, to achieve the standard requirements in term of pathogens content. Approach: Activated sludge samples were collected from Riyadh wastewater plant and analyzed quantitatively for the presence of important bacterial parameters including fecal … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 7,006 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Production Process of Biological Mineral Feed AdditivesAgnieszka Zielińska, Katarzyna Chojnacka, Marjana SimoničProblem statement: This study discussed the problem of accumulation of Zn and Cu in the topsoil as a result of application of mineral feed additives that possess low bioavailability in animal diet. The review considered the production process of mineral feed additives in which a product supplies microelements in highly bioavailable form. Enrichment of natural biomass of edible microalgae with … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,946 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioaccumulation of Cr(III) ions by Blue-Green alga Spirulina sp. Part I. A Comparison with BiosorptionKatarzyna ChojnackaThe paper presents the results of studies on kinetics and equilibrium of bioaccumulation process of Cr(III) ions by blue-green alga Spirulina sp. Bioaccumulation was described as the process that consists of two stages, passive (identical with biosorption) and active (accumulation inside the cells). The passive stage (similarly as biosorption itself) was found to be quick process and the subsequent active … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,702 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Nutritive Value of Wastewater Grown Barley and its Utilization in Fish FeedA.M. Snow, A. E. GhalyThe feasibility of using wastewater grown barley plants as a component of fish feed was evaluated. The barley plants were grown in a hydroponics system on wastewater from a recirculating aquaculture facility. The effects of wastewater application rate on plant growth and pollution potential reduction were investigated. At the end of the experiment, the average crop heights and yields were … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 7,878 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhytoremediation of Anaerobic Digester Effluent for Water Purification and Production of Animal FeedA. E. Ghaly, H.A. FaragThe application of phytoremediation for purification of an anaerobically treated dairy manure and production of forage crops was investigated. Four crops (two cereals and two grasses) were examined for their ability to grow hydroponically and to remove pollutants (nutrients) from dairy wastewater. The preliminary experiments showed that timothygrass and orchardgrass did not perform well as aquatic plants. Only 24 and … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 8,201 accessesView PDFCite
Research ArticleOpen accessIn the abstractNano TiO2 Deposited on Crude Mineral and the Photoactivity to the Degradation of ChloroformHaiyan Song, Hongfu Jiang, Xingqing Liu, Guangyao MengSupported TiO2 catalysts have increasingly attracted intention in recent years because of their potential application to photocatalytic degradation of organic pollutants in water and air. In this work, nano TiO2 particles deposited on crude nonmetallic mineral were prepared by a Sol-gel process, the photocatalyst for degradation of chloroform was tested and optimized with respect to TiO2 loading, catalyst dosage and … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 7,368 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Dose-Response of Zinc and Manganese on Siderophores ProductionMehri Ines, Khessairi Amel, Turki Yousra et al.Problem statement: This study was conducted to find and determine whether the siderophores of the four environmental Pseudomonas spp. isolates possess a sequestering activity towards essential transition metals (Zn and Mn) other than iron. Approach: Four fluorescent Pseudomonads isolated from various environments, were characterized analytically (Isoelectric focusing), biologically (pyoverdine-mediated uptake) and genetically (16S rDNA sequencing). By means of spectrophotometric measurements, … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 10 Mar 2012 · 7,768 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Integration of Network-Based Models for Spill Response and Homeland SecurityDavid E. Amstutz, Rakesh Bahadur, Jonathan M. Pickus et al.The integration of three hydraulic GIS (Geographic Information System) applications is presented which represent the water infrastructures of cities and urban areas and US streams and rivers. The water infrastructures include drinking water distribution systems, wastewater collection systems and source water. The National Research Council[1] states that problems dealing with the collective behavior of networks such as river systems, water … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,729 accessesView PDFCite
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 PDFCite
