Research ArticleOpen accessEvery word in the titleAnaerobic 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 PDF Cite

Research ArticleOpen accessIn the keywordsConformal Mapping of Temperature Variation in Compost HeapJonah Chukwuemeka Agunwamba, Oji Achuka NwokeLaboratory in vessel trapezoidal compost system was designed and constructed. Temperature variation in the compost heap was measured for five days at various depths. Mathematical model for the variation of temperature of the composting process was developed using Conformal Mapping Technique. One of the parameters in the model had two distinct roots, one a positive root and the other negative … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 17 Jun 2016 · 7,347 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUtilization of Rumen Content by Indigenous Microorganisms in a Modified Anaerobic DigesterAlhassan Salihu Adam, Sani Yahaya, Haruna Musa et al.The current work was designed to assess the effect of modification of model digester on the kinetics that affects efficiency in biogas generation using bovine rumen content as the feedstock. A biogas plant consisting of conventional and modified fixed-dome digesters (each with 2 m3 capacity) was established; and bovine rumen content was used as feedstock. Standard methods were used to … …Energy Research Journal, Vol. 11, Issue 1 · 26 Sep 2020 · 6,780 accessesView PDF Cite

InvestigationOpen accessIn the abstractMorphology, Anatomy, Chlorogenic Acid Content and Antioxidant Capacity of Xanthium strumarium L. and Xanthium spinosum L.Dinara Abdikhaliyevna Aldibekova, Murat Kizaibek, Mahaya Aisijiang et al.In this study, the morphological, anatomical features, chlorogenic acid content and antioxidant activities of two species from the genus Xanthium, namely Xanthium spinosum L. growing in the slopes of Mount Daubaba in the western part of the Talas Alatau of Tyulkibas region of the South Kazakhstan region and Xanthium strumarium L. growing in the slopes of the Alma-Arasan gorge of … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 23 May 2018 · 8,111 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnhancement 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 PDF Cite

Research ArticleOpen accessIn the abstractBiodegradation of Phenolic Compounds in Creosote Treated Wood Waste by a Composting Microbial Culture Augmented with the Fungus Thermoascus aurantiacusAbdel E. Ghaly, Bopeng Zhang, Deepika DaveProblem statement: Creosote is used as a wood preservative and water proof agent in railway sleepers, utility poles, buildings foundations and fences and garden furniture. It is a mixture of over 300 hydrocarbons which include 75% polycyclic aromatic hydrocarbons, 2-17% phenolic compounds and 10-18% heterocyclic organic compounds. Exposure to creosote may result in several health problems including damage to kidney, … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 2 · 26 Aug 2011 · 9,446 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCo-Digestion of Palm Oil Mill Effluent and Refined Glycerin Wash Water for Chemical Oxygen Demand Removal and Methane ProductionA. Sulaiman, M. R. Zakaria, M. A. Hassan et al.Problem statement: Refined Glycerin Wash Water (RGWW) from the oleochemical industry contains high Chemical Oxygen Demand (COD) and requires proper treatment before disposal. Unfortunately the wash water also contains high concentration of sodium chloride (NaCl) that could cause inhibition to the normal biological treatment process. However, there is feasibility of co-digesting the RGWW and Palm Oil Mill Effluent (POME) for … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,936 accessesView PDF Cite
