Research ArticleOpen accessIn the abstractApplication 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 PDF Cite

Research ArticleOpen accessIn the abstractGermination Study and Monitoring in the Nursery of Young Seedlings of Garcinia mangostana L.Haba Jean Florent, Dembele Ardjouma, Koffi Kouao Jean et al.Mangosteen tree (Garcinia mangostana L.) is a plant of the Clusiaceae family cultivated for its particular taste and for its excellent medicinal properties. However, the vegetative propagation of the plant by cuttings or grafting being difficult to achieve, seed germination remains the main means of production used. This study was therefore initiated with the aim of determining the influence of … …American Journal of Agricultural and Biological Sciences, Vol. 16, Issue 1 · 23 Sep 2021 · 7,440 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOverview of Membrane Processes for the Recovery of Polyphenols from Olive Mill WastewaterOmpe Aime Mudimu, Martin Peters, Florian Brauner, Gerd BraunProblem statement: Olive Mill Wastewater (OMW) is an ambivalent by-product of the olive oil production, which appears in huge amounts every year after the olive-harvest in the production countries, mainly in the Mediterranean region. OMW is characterized by a high organic load and i.a. contains considerable amounts of phytotoxical polyphenols, which cause important environmental problems. Approach: Due to their antioxidant … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 27 Mar 2012 · 8,544 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUse of a Mixture of Thermophilic Enzymes Produced by the Fungus Thermoascus aurantiacus to Enhance the Enzymatic Hydrolysis of the Sugarcane Bagasse CelluloseJ. R. Monte, W. Carvalho, A. M. F. MilagresProblem statement: The production of hydrolytic enzymes by T. aurantiacus has been performed under solid-state fermentations using lignocellulosic materials. The influences of the inoculum size and of the fermentation medium on the production of hemicellulases and cellulases were studied. Filtrates from the cultures were used to hydrolyze a pulp of sugarcane bagasse and the produced enzymes were shown to be … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 4 · 13 Dec 2010 · 9,212 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRheological Characterization of Sludge Coming from a Wastewater Treatment PlantDaniel Novarino, Ezio Santagata, Davide Dalmazzo, Mariachiara ZanettiProblem statement: The aim of this study was that of studying the rheology of sewage sludge using two different rheological test protocols taken from literature and comparing them in order to evaluate which useful information are given from every protocol. Approach: Two different protocols have been used taking particularly into account the problems connected to sludge heterogeneous composition and to … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,365 accessesView PDF Cite
