Research ArticleOpen accessEvery word in the titleBiochar Types from Latrine Waste and Sewage Sludge Differ in Physico-Chemical Properties and Cadmium AdsorptionKoetlisi Andreas Koetlisi, Pardon MuchaonyerwaPyrolysis of latrine fecal waste could produce valuable products for minimizing environmental contamination with heavy metals. The objective of this study was to determine yields, characteristics and cadmium (Cd) sorption of biochar from latrine fecal waste and sewage sludge, as affected by pyrolysis temperature. Slow pyrolysis at 350, 550 and 650°C, was used to produce the biochar. In addition to … …American Journal of Applied Sciences, Vol. 14, Issue 11 · 30 Nov 2017 · 8,512 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUtilization of Sewage Sludge in Agricultural Soil as Fertilizer in the Republic of Benin (West Africa): What are the Risks of Heavy Metals Contamination and Spreading?Fidèle Suanon, Lyde A.S. Tomètin, Biaou Dimon et al.Biosolids are the treated organic residuals, also known as sewage sludge, which are generated from domestic wastewater treatment plants. It is an organic matter and nutrients [phosphorous (P) and nitrogen (N)]-rich material. Due to these properties, it is has been reported to be a suitable fertilizer or soil amendment which can valuably replace synthesized NPK. Unfortunately, this matter is heavily … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 6 Jan 2016 · 14,496 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnaerobic Digestion of Pulping Wastewater Using Up-flow Anaerobic Sludge Blanket (UASB) Reactor at Mesophilic ConditionRanda M. Osman, M. HamadThe waste considered for this study was the effluent of the pulping process produced during the manufacture of pulp and paper in the Rakta integrated pulp and paper mill in Alexandria. The pulping process in Rakta mill is conducted under pressure of 7-8 bar, 165°C using 10% NaOH based on straw weight for 2 h.

Research ArticleOpen accessEvery word in the titleAssessment of Heavy Metals Uptake and Translocation by Aquilaria malaccensis Planted in Soils Containing Sewage SludgeKeeren Sundara Rajoo, Arifin Abdu, Hazandy Abdul-Hamid et al.Increase in human population has resulted in an enormous growth in the volume of wastewater. The conventional methods of sewage sludge disposal, that is the by-product of wastewater treatment, are costly and not environment-friendly. An ideal way for sewage sludge management is by using it as a soil amendment in agricultural land due to sewage sludge’s high organic matter content. … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,079 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHeavy Metal Uptake and Translocation by Dipterocarpus verrucosus from Sewage Sludge Contaminated SoilKeeren Sundara Rajoo, Arifin Abdu, Daljit Karam Singh et al.Sewage sludge or biosolids is the solid waste that has been left after wastewater is treated in a domestic wastewater treatment facility. The most common way of sludge disposal is to dispose it on the land, sea or air (incineration). However, these methods are not environment-friendly, costly and time consuming that requires expertise and knowledge. An ideal way to manage … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 10 Jul 2013 · 7,819 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Pressure, Water Depth and Water Flow Rate on Oxygen Saturation Level in Activated Sludge ProcessNabil N. Atta, Amro A. Elbaz, Alhassan H. SakrProblem statement: The role of aeration in activated sludge process is to provide oxygen to microorganisms as they assimilate the organic carbon compounds and digest a portion of them to carbon dioxide and water, sulfate and nitrate compounds. The water aeration equipment used in this process consumes as much as 60-80% of total power requirements in modern wastewater treatment plants. … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 21 Dec 2011 · 8,741 accessesView PDFCite
