Research ArticleOpen accessIn the abstractUsing Permeable Reactive Barriers to Remediate Heavy Metal-Contaminated Groundwater through a Laboratory Column ExperimentSomean Yin, Gemunu Herath, Sokchhay Heng, Senajith KalpageRecently, groundwater sources are being polluted by various activities such as agriculture, livestock, decentralized wastewater treatment systems and acid rain. Groundwater can also be polluted by landfill leachate, sewage, mine tailings, non-engineered deep well disposal of liquid waste and seepage from industrial waste lagoons. There are many studies reported contaminated groundwater remediation using Permeable Reactive Barrier systems (PRBs) and many … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Mar 2017 · 8,761 accessesView PDFCite
Research ArticleOpen accessIn the abstractNitrifying, Denitrifying and Heterotrophic Biomass Present in Moving Bed-ReactorAndreliza Carolina Del Grossi Oliveira, Camila Zoe Correa, Kátia Valéria Marques Cardoso Prates, Deize Dias LopesThis study was carried out to evaluate the main bacterial communities related to the removal of nitrogen in a moving bed-reactor treating landfill leachate, relating the physico-chemical parameters with the existence of these organisms in the mixed liquor (non-attached microorganisms) and Support Material (SM). The system was operated in two phases: Phase I (without effluent recirculation) and II (with recirculation, … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 25 Jan 2017 · 7,628 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption of Nickel and Zinc by Residual SoilsNur ’Aishah Zarime, W. Y. Wan Zuhairi, Sivarama KrishnaSoil has long been utilized as low cost liner material to prevent contamination from leachate to groundwater media. To find a suitable soil material for this purpose is a great challenge. This study describes the potential use of residual soil to functions as engineered clay liner for waste disposal landfill in Malaysia. Three types of residual soils were investigated namely … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 5 Dec 2014 · 7,116 accessesView PDFCite
Research ArticleOpen accessIn the abstractINVESTIGATING THE STANDARD PROCESS OF INCINERATION IN LANGKAWI ISLAND, MALAYSIAE. Shamshiry, M. Bin Mokhtar, A.M. AbdulaiDevelopment activities and increasing urbanization have direct impact on solid waste generation, especially in municipalities of the developing countries, which poses a major challenge to the authorities. Many various technologies and strategies can be used in the field of garbage procedures. Incineration is a well-organized approach and tool to decrease the volume of waste and insist for additional landfill area. … …American Journal of Environmental Sciences, Vol. 10, Issue 3 · 2 May 2014 · 7,884 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Constructed Wetland Biological Integrity Using Aquatic MacroinvertebratesC. Galbrand, I. G. Lemieux, Abdel E. Ghaly et al.A surface flow constructed wetland consisting of seven cells was used to treat the leachates from a decommissioned landfill. Wetland monitoring was performed by evaluating the treatment efficiency of the landfill leachate and the wetland biological integrity of the wetland. The water quality samples were analyzed for iron, manganese, phosphorus (orthophosphate), pH, dissolved oxygen (DO), nitrogen (ammonia, nitrate, nitrite and … …OnLine Journal of Biological Sciences, Vol. 7, Issue 2 · 31 Dec 2007 · 7,415 accessesView PDFCite
Case ReportOpen accessIn the abstractOutlook of Municipal Solid Waste in Bogota (Colombia)José Alejandro Martínez SepúlvedaThe Municipal Solid Waste is a new target of the municipal government because their negative consequences if the management is inadequate (health diseases, pollution, etc.); In Latin America, the most frequency solution is the final disposal in landfill, but, no-all the Solid Waste is really waste (or unusable material): (i) The Inorganic Fraction that, for the no source separation, lost … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 2 Mar 2016 · 9,090 accessesView PDFCite
Research ArticleOpen accessIn the abstractTYPICAL MEXICAN AGROINDUSTRIAL RESIDUES AS SUPPORTS FOR SOLID-STATE FERMENTATIONDulce A. Flores-Maltos, Solange I. Mussatto, Juan C. Contreras Esquivel et al.Biological wastes contain several reusable substances of high value such as soluble sugars and fiber. Direct disposal of such wastes to soil or landfill causes serious environmental problems. Thus, the development of potential value-added processes for these wastes is highly attractive. These biological wastes can be used as support-substrates in Solid-State Fermentation (SSF) to produce industrially relevant metabolites with great … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 18 Mar 2014 · 7,473 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Electricity Planning Comprise Renewable Energy and Feed-In TariffHo Wai Shin, Haslenda HashimProblem statement: Mitigation of global warming and energy crisis has called upon the need of an efficient tool for electricity planning. This study thus presents an electricity planning tool that incorporates RE with Feed in-Tariff (FiT) for various sources of Renewable Energy (RE) to minimize grid-connected electricity generation cost as well as to satisfy nominal electricity demand and CO2 emission … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 28 Feb 2012 · 8,695 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of the Detoxification on the Shrinkage Temperature and pH of Chromium Leather Waste, Another Promising Way for the Tannery PollutionA. Malek, M. HachemiThe leather tannery industry produces a significant amount of solid chromium waste. Environmental concerns and escalating landfill costs are becoming increasingly serious problems to the leather industry and alternative disposal methods are needed. This research describes the possibility of decrease of the shrinkage temperature and to increase the pH value of leather waste by detoxification treatment with use of tartrate … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,114 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvolution of Biochemical Parameters During Composting of Various Wastes CompostN. Saidi, M. Cherif, N. Jedidi et al.In Tunisia the most treatment waste is landfill (50% of wastes were land filled) and only 5% are composted. And since our soil become more and more poor in organic matter, green waste can be a significant source of organic matter; in parallel we cited the domestic waste and dead posodonia collected from beaches. All these wastes coming from various … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,933 accessesView PDFCite
