Research ArticleOpen accessPhrase in the titleKinetics of Biological Treatment of Low Level Pesticide WastewaterAbdel E. Ghaly, Deepika DavePesticides are chemical substances intended to protect food crops and livestock from pests in order to pro-mote agricultural productivity and protect public health. Contamination of soil, air and water and threat to human and animal health are the major constraints in the use of pesticides. Treatment of pesticide contaminated water is, therefore, paramount. Biological treatment provides the most economical option … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 4 Jul 2012 · 8,163 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleIntermittent Aeration in Biological Treatment of WastewaterH. Doan, A. LohiProblem statement: E-coating process is widely used to provide a protective coating layer on metal parts in the automotive and metal finishing industry. The wastewater from the coating process contains organic compounds that are used in the cleaning, pretreatment and coating steps. Organic pollutants can be removed biologically. In the aerobic biological treatment, water aeration accounts for a significant portion … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,131 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Development in Biological Process for Wastewater Treatment to Produce Renewable FuelKadhum M. Shabeeb, Khalid A. Sukkar, Rana A. Azeez et al.Problem statement: Hydrogen is a clean energy source. Bio-conversion of biomass to generate hydrogen has been achieved using anaerobic fermentation of some well-defined materials, in wastewater. No data available on hydrogen yielded from wastewater using inoculum extracted from Iraqi municipal wastewater treatment plant. Approach: This study investigated the effects of substrate concentration, initial pH and process temperature on biohydrogen production … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,252 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleStudy of Different Types of Enzymes for Biological, Agro-Food Processing and Industrial Wastewater Treatment: An OverviewABM Sharif Hossain, Musamma M UddinThe objective of the review study was carried out from different research data to find out the innovative latest information on the waste water treatment in agro, industrial and municipal areas. From the review study, it has been noted that cellulase, peroxidage, lignage, tyrosinase, pactinase and amylase have been widely used for waste water treatment. Besides, microbial enzymes such as … …American Journal of Environmental Sciences, Vol. 17, Issue 4 · 7 Sep 2021 · 6,692 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEfficient Design of a Photovoltaic Water Pumping and Treatment SystemAbderrahmen Ben Chaabene, Med Faouzi Elkaroui, Anis SellamiThrough the world, the exploitation of solar energies knew a strong growth these last years. It is interesting to exploit them on the place of consumption, by directly transforming into heat, or in electricity according to needs and especially in remote areas where power from utility is not available or is too costly to install. The use of photovoltaic sources … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 4 Jul 2013 · 7,628 accessesView PDFCite
Research ArticleOpen accessIn the keywordsReview on Landfill Leachate TreatmentsAbdulhussain A. Abbas, Guo Jingsong, Liu Zhi Ping et al.Problem Statement: Sanitary landfilling is the most common way to eliminate solid urban wastes. An important problem associated to landfills is the production of leachates. This study is a review of landfill leachate treatments. Approach: The advantages and disadvantages of the various existing leachate treatments discussed under the items: (i) Leachate channeling (combined treatment with domestic sewage, recycling) (ii) Biological … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 13,754 accessesView PDFCite
