Research ArticleOpen accessIn the abstractTreatment of Wastewater by Natural Lagoon for its Reuse in IrrigationM. Driche, D. Abdessemed, G. NezzalThe process of natural lagoon consists in purifying the waste water by simple flow of the effluent in not very deep ponds where proliferate bacteria, algae and other living organisms, under a surrounding air and in the presence of a solar radiation. For this study, which is spread out over 3 years (2004-2006) and which still continues, we chose the … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,187 accessesView PDFCite
Research ArticleOpen accessIn the abstractDead Sea Rate of EvaporationAbdelaziz L. AL-KhlaifatThe Dead Sea is exceptional by many standards. It is the saltiest and lowest lake in the world. Moreover it is a closed lake with very large variations in its water level caused by both man-made and natural oscillations of the components that make up the water balance. Most of the fundamental studies on the Dead Sea focused on the … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,542 accessesView PDFCite

TarawnehJordan’s natural resources are limited to support population in a sustainable manner. However, its environment is exposed to a number of threats. In order to best explain Jordan’s environmental difficulties, it would be prudent to focus individually on each of these major concerns: water shortages, agriculture/land and air pollution. This study focuses on the environmental problems in Jordan and has … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 10,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Total Dissolved Solids on Aquatic Organisms: A Review of Literature and Recommendation for Salmonid SpeciesPhyllis K. Weber-Scannell, Lawrence K. DuffyTotal dissolves solids (TDS) are naturally present in water or are the result of mining or some industrial treatment of water. TDS contain minerals and organic molecules that provide benefits such as nutrients or contaminants such as toxic metals and organic pollutants. Current regulations require the periodic monitoring of TDS, which is a measurement of inorganic salts, organic matter and … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Jan 2007 · 23,417 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Removal of 4-Chlorophenol and Dichloroacetic Acid in Water Using Ti-, Zr- and Ti/Zr-Pillared Bentonites as PhotocatalystMohamed Houari, Mohamed Saidi, Djamel Tabet et al.Heterogeneous photocatalysis could be alternative remediation technology for water since it does not need the addition of any chemicals and it is suitable for treating low concentrations of pollutant. Although the TiO2 Degussa P 25 is most used photocatalyst its photonic efficiency still low and its recovery from water is considered as an awkward process. In this study the effect … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 7,523 accessesView PDFCite
