Research ArticleOpen accessIn the abstractA Review of Integrated River Basin Management for Sarawak RiverKuok King Kuok, Sobri Harun, Po-Chan ChiuProblem statement: Sarawak River was a life-sustaining water source for the residents in Kuching City and surrounding areas. Raw water is treated at Batu Kitang Water Treatment Plant (BKWTP) that supplies more than 98% of the total water production in Kuching City. The raw water supply to BKWTP is not adequate to meet the ever increasing water demand. In order … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 21 Jul 2011 · 9,100 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption of Methylene Blue from Aqueous Solution onto a Low-Cost Natural Jordanian TripoliAtef S. ALzaydienProblem statement: It is well documented that lead is one of contaminants of industrial wastewaters and its pollution exists in the wastewater of many industries. As a result, recent research has focused on the development of cost effective alternatives using various natural sources and industrial wastes. In this setting, the use of low-cost agricultural materials, waste and residues for recovering … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,949 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Cadmium (II) Ions Biosorption onto Pretreated Dried Activated SludgeR. Darvishi Cheshmeh Soltani, A. Jonidi Jafari, Gh. Shams KhorramabadiProblem statement: Heavy metals have been one of hazardous components in industrial effluents that can be damaged on the environment by discharging uncontrolled wastewater. The aims of this investigation were biosorption of Cd (II) ions onto pretreated dried activated sludge and determination of kinetic and isotherm of biosorption. Approach: Activated sludge was obtained from Tehran municipal wastewater treatment plant. Activated … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,713 accessesView PDFCite
Research ArticleOpen accessIn the abstractELECTROLYSIS OF SWINE MANURE EFFLUENTS USING THREE DIFFERENT ELECTRODES Fe-Fe, Al-Al AND Fe-AlS. Rahman, M. S. BorhanSwine effluent with high organic strength need to be treated to make it suitable for applying to crop/pasture fields, or discharging to any waterways. Electrocoagulation is a relatively simpler and cheaper technique over biological and chemical treatment methods currently used to treat high-strength industrial and municipal wastewater. The performance of an electrocoagulation system mainly depends on the pH, Electrical Conductivity … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 4 · 9 Oct 2014 · 9,182 accessesView PDFCite
Research ArticleOpen accessIn the abstractRAPID DEGRADATION OF AZO DYES USING NANO-SCALE ZERO VALENT IRONNabila Rahman, Zainal Abedin, M. Ali HossainIn the present study, nano-scale Zero Valent Iron (NZVI) was synthesized in ethanol medium by the method of ferric iron reduction using sodium borohydride as a reducing agent under atmospheric conditions. The obtained iron nanoparticles are mainly in zero valent oxidation state and remain without significant oxidation for hours. A systematic characterization of NZVI was performed using XRD, SEM and … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 8 Apr 2014 · 8,605 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiosorption of Textile Dye Using Immobilized Bacterial (Pseudomonas aeruginosa) and Fungal (Phanerochate chrysosporium) CellsNatarajan Saravanan, Tiruvenkadam Kannadasan, Chiya Ahmed Basha, Veerasamy ManivasaganWastewater containing dyes presents a serious problem due to its high toxicity which leads to creating enormous environmental pollution and ecological hazards. Therefore the removal of the high stable dyes from the textile effluents is of major importance. The purpose of this study is to remove the reactive dye Procion Blue 2G from textile dye solution by biosorption process using … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 16 Sep 2013 · 7,358 accessesView PDFCite
Research ArticleOpen accessIn the abstractHexavalent Chromium Removal by Litchi chinensis Sonn PeelIsmael Acosta-Rodriguez, Rigoberto Martinez-Perez, Juan F. Cardenas-Gonzalez et al.Problem statement: We studied the Chromium (VI) removal capacity in aqueous solution by the litchi peel. Approach: We use the diphenylcarbazide method to evaluate the metal concentration. Results: The highest biosorption of the metal (50 mg L-1) occurs within 6 min, at pH of 1 and 28°C. According to temperature, the highest removal was observed at 40 and 50°C, in … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 1 · 1 Mar 2012 · 8,229 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Modeling of Flow in a Horizontal Sand FilterRuth Mossad, Hal AralProblem statement: Horizontal sand filters may offer some advantage over vertical sand filters as they could be used for in-line treatment of wastewaters. Horizontal pipelines of tens and if not hundreds of meters length, filled with ordinary sand or permeable reactive media such as activated carbon or natural zeolite or iron filings, may be used to remove impurities from mine … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,508 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 · 6,950 accessesView PDFCite
