Research ArticleOpen accessAll words, across the recordReduction of Microbial Contamination of Outlet Waste in Urban Wastewater Treatment PlantsSona Pazdar, Saeid Eslamian, Hossein Gholami, Kaveh Ostad-Ali-AskariThe available research was managed to monitor the physicochemical and microbiological features of treatment plants. The wastewater treatment herb sewage is a straight pollution input source for anthropogenic pollution. The sediment information ideas to an urban drainage trench as a secondary point pollution source while the organotins information highlights the presence of other spread sources, special to this material. wastewater … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 18 Sep 2019 · 7,607 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordReprocess of Copper from Worn Printed Circuit BoardsSwarnambiga A.K., M. Vidya Kalaivani, Sarah Sathyawathi, T.S. Ramyaa LakshmiThe objective of the study is to reuse printed circuit boards which are mainly made of copper. Most top down and bottom up approaches for the synthesis of Copper nanoparticles (CuNPs) needs pure copper (II) sulfate or any other copper salts as a raw material. For the expensive non-ecofriendly reasons, here we used wasted Printed Circuit Boards (PCBs) as an … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 12 Feb 2019 · 7,484 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Effect of Natural Water with Cow Dung and Agricultural Waste Ratio on Biogas Production from Anaerobic Co-DigestionNaponKeanoi, KanokornHussaro, Sombat TeekasapGlobal warming caused by energy generation from fossil fuel has accelerated the deployment of renewable fuels such as biogas. In this study, batch fermentation (5L) was studied to observe the effect of natural water, cow dung, rice straw and water hyacinth ratio on the biogas and methane production at ambient temperature (31°C), 7.1-7.4 of pH for 52 days. The five … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 22 Jan 2014 · 8,508 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMechanical Properties of Waste Biaxially Oriented Polypropylene Metallized Films (BOPP), LLDPE: LDPE Films with Sisal FibresKiran Rohit, Savita DixitThe current work describe the enhancement and improvisation of polymer composite repose of sisal fiber reinforcement, Biaxially Oriented Polypropylene (BOPP) and thermoplastic LLDPE: LDPE particulate fillers. The composite were prepared with fiber content 5, 10, 15 and 20% (by weight). The composite are characterized with respect to their mechanical properties (Tensile, flexural and impact strength) were studied. Tensile strength showed … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 2 Nov 2016 · 8,374 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Effects of Briquetting Pressure on Banana-Peel Briquette and the Banana Waste in Northern ThailandPatomsok WilaiponBanana is considered as one of the most important agricultural products of Northern Thailand. A large amount of banana peel has been left as garbage after industrial processes. The raw material is plentiful and has low economic value. Therefore, the characteristics of banana-peel briquettes including banana peel properties were investigated. The briquettes were produced with pressures ranging from 3 to … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 11,911 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPhysical Characteristics of Maize Cob Briquette under Moderate Die PressurePatomsok WilaiponThe potential energy content of maize cob available in Thailand was calculated based on maize productivity, the residue-to-product ratio and the heating value of maize cob. It was found that the computed value was about 74.2 PJ/year. Besides, the potential energy value exceed 1,000 TJ/year was also reported for the case of five provinces of Thailand. Concerning with maize cob … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 8,087 accessesView PDFCite
