Research ArticleOpen accessPhrase in the titleApplication of Polyelectrolyte in Turbidity Removal from Surface WaterA. H. Mahvi, M. RazaviOne of the most important treatment processes in surface water treatment plants is coagulation. Surface waters such as rivers and lakes contain suspended particles and turbidity. With the aid of coagulants, and by flocculation process, followed by sedimentation and filtration, these impurities can be removed from raw waters these days, besides conventional chemicals such as Alum and Ferric chloride, polymers … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 8,237 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimizing Coagulation Process for Low to High Turbidity Waters Using Aluminum and Iron SaltsAkbar Baghvand, Ali Daryabeigi Zand, Nasser Mehrdadi, Abdolreza KarbassiProblem statement: Turbid waters, containing colloidal particles, are normally treated by coagulation-flocculation followed by clarification. Ferric chloride and alum, which are the most common types of coagulants in water treatment plants of Iran as well as many other countries, were investigated with the aim of determining their capabilities to reduce turbidity of drinking water. Turbidity was added as kaolin. Optimization … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 21,079 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordRemoval of Hydrogen Sulphide from WaterS. Edwards, R. Alharthi, A.E. GhalyProblem statement: The concentration of H2S in groundwater is a significant problem in various areas across Canada. Hydrogen sulphide dissolves in ground water imparting undesirable taste and irritating rotten egg smell which makes it unpalatable. Ingestion of sulphides through drinking water can result in stomach discomfort, nausea and vomiting. Humans exposed to high concentrations of H2S for prolonged periods show … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 26 Aug 2011 · 15,123 accessesView PDFCite
