Research ArticleOpen accessEvery word in the titleTreatment of Landfill Leachate using Limestone/Sandstone Filters Under Aerobic Batch ConditionsAbdel E. Ghaly, M.A. Kamal, N.S. Mahmoud, R. CoteThe suitability of a passive technology, consisting of filters composed of a mixture of limestone and sandstone rocks, for the treatment of landfill leachates containing 6.6 mg Lˉ1 iron and 1.8 mg Lˉ1 manganese were investigated. The limestone and the limestone/sandstone filters successfully removed iron from the prepared solutions. The filters removed on average a minimum of 97.60% of the … …American Journal of Environmental Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 7,066 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Temperature on the Performance of Limestone/Sandstone Filters Treating Landfill LeachateAbdel E. Ghaly, M.A. Kamal, R. CoteThe ability of limestone and limestone/sandstone filters to remove dissolved iron and manganese from landfill leachate under field conditions were investigated. The results showed that the precipitation of iron and manganese were affected by temperature and time. Most of iron was removed from solution within the first 10 min at 20°C while the removal of iron from solution took much … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 7,109 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRemoval of Coliform Content in Sewage Treatment Plant Using a Sand Filtration System with Potassium Permanganate PowderSona Pazdar, Saeid Eslamian, Seyedeh Zahra Hosseini-Teshnizi et al.Reuse of refined sewage with two goals of providing more water and protecting the environment from pollution is one of the solutions to water supply problems and one of the potential sources for irrigation in agriculture. The aim of this study is to evaluate the possibility of effluent disinfection using a sand filtration system to reduce microbial contamination with potassium … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 27 Jun 2019 · 7,583 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAdsorption and Distribution of Selected High Molecular Weight Polycyclic Aromatic Hydrocarbons in a Typical Coastal Sand DepositUzoije Atulegwu Patrick, Ezenobi Chukwunoye ChristainContaminant migration study through soil medium is a veritable tool for a match towards sustainable groundwater protection. It is also essential to predict the fate and Transport of pollutants and to evaluate pollution risks. In this study, migration and distribution of High Molecular Weight (HMW) Polycyclic Aromatic Hydrocarbons (PAHs) through a coastal sand deposit of a wetland was investigated. Flow … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 27 Mar 2018 · 7,360 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFatigue Life Prediction of Screw Blade in Screw Sand Washing Machine under Random Load with Gauss DistributionJie Gong, Yun-Fei Fu, Wen Xia et al.The purpose of this study is to present a new method for estimating the fatigue life of the screw blade in the screw sand washing machine. To ensure the accuracy of numerical simulation, the loading area and the value of load are determined by means of the theoretical analysis. To ascertain the location of the stress peak and stress range, … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 22 Dec 2016 · 8,005 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHeterogeneities and Intra Sand-Body Compartmentalization in Late Oligocene Delta-Front Deposit, Niger Delta, NigeriaRaphael Oaikhena Oyanyan, Michael Ndubuisi OtiThis paper presents the study of the heterogeneity in lithofacies, porosity, permeability, mineral grain density, pore-throats sizes and hydraulic rock types and the intra sand-body compartmentalization in cored delta-front deposit of Greater Ughelli depobelt of Niger Delta. Sedimentological study of core samples results in the identification of nine lithofacies and the interpretation of environments of deposition as mainly proximal and … …Current Research in Geoscience, Vol. 6, Issue 1 · 28 Mar 2016 · 8,090 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSedimentology and Depositional Environment of D2 Sand in Part of Greater Ughelli Depobelt, Onshore Niger Delta, NigeriaPrince Suka Momta, Jonathan O. Omoboh, Minapuye I. OdigiThe sedimentology and depositional environment of D2 sand in part of the Greater Ughelli depobelt have been studied using well logs and core data. Three wells were correlated to establish the lateral continuity of the D2 sand across the field and standard gamma ray log trends was used to infer depositional environments. Cored section of well B was described to … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 19 Sep 2015 · 8,585 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAerosol Filtration Using Quartz Sand FilterAbbas H. Sulaymon, Yasmen A. MustafaThe cement industry is the major source of cement dust which contains heavy metals like nickel, cobalt, lead, chromium, arsenic and hazardous substances like dioxins and furans. Exposure to these substances can cause health problems to human, animals and vegetation. A continuous pilot scale quartz sand filter was constructed and uses to study the effect of important design parameters (temperature, … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 20 Jun 2012 · 7,716 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRational Mix Design Approach for High Strength Concrete Using Sand with very High Fineness ModulusKwan Wai Hoe, Mahyuddin RamliProblem statement: Production of concrete is always deal with inconsistency. Sources of variation like materials from different geographical basis, mix design method, fineness of aggregates and so on will attribute to different level of achievement of the concrete. Even though researcher had verified that higher fineness modulus of sand would yield better performance for the concrete, but so far there … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 8,217 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSugarcane Response to Water-Deficit Stress during Early Growth on Organic and Sand SoilsDuli Zhao, Barry Glaz, Jack C. ComstockProblem statement: Approximately 20% of sugarcane (Saccharum spp.) is grown on sand soils in south Florida, USA. Sugarcane yields in the region linearly increased in last 33 years on organic (muck) soils, but not on sand soils. Water deficit during the formative growth phase on sand soils probably limits sugarcane yields. Approach: A greenhouse study was conducted in 2009 and … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 10,260 accessesView PDFCite
