Approach: The carbon and the nitrogen of the microbial biomass (BC and BN) were studied using the fumigation-extraction method. Results: The dynamics of the BC/BN ratio, index of the chemical composition of the whole … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 6,702 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis of Zeolite A from By-Product of Aluminum Etching Process: Effects of Reaction Temperature and Reaction Time on Pore VolumeKanokorn Hussar, Sombat Teekasap, Nisakorn SomsukProblem statement: Increasing of the carbon dioxide (CO2) concentration in the atmosphere creates a global warming. Zeolite is used as CO2 absorbent. Approach: By-products from aluminum etching process, which carry a large amount of Al2O3 content, are useable as raw materials for synthesis zeolites type A using hydrogel process. A pore volume of zeolites is the key to achieve high … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,836 accessesView PDFCite
Research ArticleOpen accessIn the abstractModelisation of Nitrification under Inhibited Environment by Moving Bed Bio-Film Reactor TechniquePham Thi Hong Duc, Le Van Cat, Jean-Luc VaselProblem statement: Nitrification by Moving Bed Biofilm Reactor (MBBR) involves physical, chemical and biological processes to remove toxic ammonia for aquaculture that are governed by a variety of parameters, like substrate and dissolved oxygen concentrations, organic matters, temperature, pH, alkalinity and turbulence level, which impact negatively or positively on nitrification kinetics. Approach: The situation becomes more serious as the reaction … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 6,946 accessesView PDFCite
