Research ArticleOpen accessIn the abstractAnaerobic Digestion of Pulping Wastewater Using Up-flow Anaerobic Sludge Blanket (UASB) Reactor at Mesophilic ConditionRanda M. Osman, M. HamadThe waste considered for this study was the effluent of the pulping process produced during the manufacture of pulp and paper in the Rakta integrated pulp and paper mill in Alexandria. The pulping process in Rakta mill is conducted under pressure of 7-8 bar, 165°C using 10% NaOH based on straw weight for 2 h. The spent liquor after alkali … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 11 Aug 2015 · 6,927 accessesView PDFCite
Research ArticleOpen accessIn the abstractRegeneration of Lyes for Cleaning-In-Place (CIP) Processes in Dairies: Comparison of Recycled Potash and Soda Solutions Cleaning PropertiesMarie Furic, Anne Elain, Walid Blel, Olivier SireThe regeneration of lyes for their integration in the dairy CIP was investigated applying an original process combining adsorption/coagulation and flocculation operations. Solutions of potassium hydroxide (KOH) and caustic soda (NaOH) soiled with 1% (v/v) of whole milk were submitted up to twenty successive regeneration cycles. The multiple recycling of the regenerated solutions was found to modify their physicochemical characteristics … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 6 Jul 2015 · 6,624 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffectiveness of Photocatalytic Decolourization of Reactive Red 120 Dye in Textile Effluent Using UV/H2O2Rishi Ananthashankar, Abdel GhalyThe effectiveness of Advanced Oxidation Process (AOP) for degradation of reactive red 120 dye in aqueous solutions was tested in this present study. Ten different concentrations of the reactive red 120 dye were exposed to UV alone and a combination of UV with two different concentrations (10 ml/L and 20 ml/L) of H2O2 for 10 different retention times at the … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,408 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Policy for Path Selection in Dynamic Source Routing Protocol for Mobile Ad-Hoc NetworksRagb O.M. Saleh, Md Yazid Mohd Saman, M. Nordin A. RahmanIn standard DSR protocol, nodes automatically discover and maintain the routes in the network by storing source routes, discovered dynamically on-demand. They maintain route caches that contain the source routes which the node is aware of. Entries are continually updated when new routes are learned and reorder the cached routes according to the traditional shortest path policy. The problem with … …Journal of Computer Science, Vol. 9, Issue 5 · 17 May 2013 · 6,216 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Effective Passive Solar Dryer for Thin Layer Drying of Poultry ManureA. E. Ghaly, K. N. MacDonaldAnimal and poultry manures have been recognized for centuries as organic fertilizers providing essential nutrients to crops and improving soil structure due to their large input of organic matter. Increasing demand for poultry and egg products has led to intensification of the poultry rearing process, resulting in large amounts of poultry manure. Drying can be used to reduce the environmental … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 4 Aug 2012 · 10,310 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Innovative Farm Scale Biogas/Composting Facility for a Sustainable Medium Size Dairy FarmA.E. Ghaly, M. Al HattabApproach: The amount of energy related costs as a portion of the total farm operating cost can be as high as 29% and the continuing increase of the real cost of energy related farm input has been one of the major factors impacting the cost of agricultural production. However, agricultural has the potential of replacing some of the purchased energy … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 5 Jan 2012 · 9,320 accessesView PDFCite
