Research ArticleOpen accessEvery word in the titleINCREASING ANAEROBIC DIGESTION PERFORMANCE OF WASTEWATER WITH CO-DIGESTION USING DECANTER CAKEThaniya Kaosol, Narumol SohgrathokLow biogas production in the frozen seafood wastewater anaerobic digestion is observed due to the low organic and Total Solids (TS) contents in the wastewater. In this research the decanter cake will be used in the anaerobic co-digestion process to improve the biogas production rate. The effect of co-digestion and Hydraulic Retention Time (HRT) will be investigated using the continuously … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 22 Sep 2014 · 7,359 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEnhancement of Biogas Production Potential for Anaerobic Co-digestion of Wastewater using Decanter CakeThaniya Kaosol, Narumol SohgrathokThe wastewater from agro-industry treated with the biological treatment cannot produce the biogas because of its low COD level and its low organic content. In this research, the co-digestion with decanter cake will improve the biogas yield and biogas production of wastewater. The effect of three parameters (i.e., type of wastewater, mixing and mesophilic temperature) will be evaluated in batch … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 1 · 15 Mar 2013 · 7,717 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOlive Wastewaters' Impact on Oued Boufekrane in Meknes-TafilaletMajdouline Larif, Abdelmajid Soulaymani, Mohammed Hnach, Azzedine ElmidaouiProblem statement: Water quality of river Boufekrane is subject to heavy pollution exerted by population growth and industrial activity, including the OMW from the olive industry in which the presence of polyphenols and toxic effect dominant character may generate a higher organic pollution. Approach: Our objective is to "study the impact of OMW by analyzing the physicochemical parameters on seven … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 20 Apr 2012 · 7,514 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOverview of Membrane Processes for the Recovery of Polyphenols from Olive Mill WastewaterOmpe Aime Mudimu, Martin Peters, Florian Brauner, Gerd BraunProblem statement: Olive Mill Wastewater (OMW) is an ambivalent by-product of the olive oil production, which appears in huge amounts every year after the olive-harvest in the production countries, mainly in the Mediterranean region. OMW is characterized by a high organic load and i.a. contains considerable amounts of phytotoxical polyphenols, which cause important environmental problems. Approach: Due to their antioxidant … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 27 Mar 2012 · 8,544 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePermeability, Strength and Filtration Performance for Uncoated and Titania-Coated Clay Wastewater FiltersMasturi, Silvia, Mahardika Prasetya Aji et al.Problem statement: Wastewater problems continue to be a relevant issue, particularly in urban areas. One promising low-cost material for manufacturing porous ceramics as water filter is clay. Clays can be blended with other materials such as polymers to obtain functional ceramic materials. Approach: Ceramic wastewater filters were fabricated from clay using both sol-gel and simple mixing methods followed by hot-pressing … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 29 Feb 2012 · 8,395 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhysicochemical and Microbial Caracteristics Performency in Wastewater Treated Under Aerobic ReactorAsma Ben Rajeb, Hamadi Kallali, Neila Saidi et al.Problem statement: The current work study the efficiency of biological wastewater treatment by an aerobic reactor which could be used in small agglomerations. RBC reduced physicochemical and microbiological load of wastewater but values remain above Tunisian standard. Approach: Experiments were conducted on a sand filled PVC column fed with wastewater treated by Rotating Biological Contactor (RBC) at a pulsed rhythm … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 6,676 accessesView PDFCite
