Research ArticleOpen accessPhrase in the titleCo-Digestion of Palm Oil Mill Effluent and Refined Glycerin Wash Water for Chemical Oxygen Demand Removal and Methane ProductionA. Sulaiman, M. R. Zakaria, M. A. Hassan et al.Problem statement: Refined Glycerin Wash Water (RGWW) from the oleochemical industry contains high Chemical Oxygen Demand (COD) and requires proper treatment before disposal. Unfortunately the wash water also contains high concentration of sodium chloride (NaCl) that could cause inhibition to the normal biological treatment process. However, there is feasibility of co-digesting the RGWW and Palm Oil Mill Effluent (POME) for … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,936 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimization of a Combined Approach for the Treatment of Carbide Slurry and Capture of CO2Shereen Hasan, Muftah H. El-NaasThe aim of this study is to evaluate the potential use of electrocoagulation in the treatment of carbide slurry, a wastewater generated during the production of acetylene, and in the capture of carbon dioxide. An electrochemical batch reactor was used to carry out several experiments at different current densities, ranging between 140-290 A/m2.
