Item type: Item , Emisión de compuestos orgánicos volátiles (voc) durante el compostaje de biosólidos provenientes de plantas de tratamiento de aguas residuales domésticas(Universidad de Los Andes, 2001) Claudia Ximena Ramos; Sandra L Estévez; Eugenio GiraldoThis work presents the results of VOC’s emitted during the wastewater biosolids composting in two static piles. VOC’s were isolated by Solid Phase Microextraction (SPME) and analysed by Gas Chromatography/Mass Spectrometry (GC/MS). More than 150 organic compounds were identified including aliphatic and aromatic hydrocarbons, chlorinated compounds, ketones, mercaptans, sulfides, alcohols and amines, a must of them in concentration above the USEPA inhalation standards.Item type: Item , International Opportunities for Energy Management: Latin American Utilities and What We Can Learn from Them(Water Environment Federation, 2016) Katy Lackey; Lauren Fillmore; Carmen Rosa Yee-Batista; Juan Pablo Rodríguez; Eugenio GiraldoItem type: Item , International Opportunities for Energy Management: Latin American Utilities and What We Can Learn from Them(Water Environment Federation, 2015) Katy Lackey; Lauren Fillmore; Carmen Rosa Yee-Batista; Juan Pablo Rodríguez; Eugenio GiraldoItem type: Item , Sistema de control de un reactor anaerobio utilizado en el tratamiento de las aguas residuales industriales(Universidad de Los Andes, 1995) Mauricio Duque; Eugenio Giraldo; Franklin Bello; Ian Carlos Ortiz; Luis Carlos Castro SerranoSistema De Control De Un Reactor Anaerobio Utilizado En El Tratamiento De Las Aguas Residuales IndustrialesItem type: Item , Tratamiento de lixiviados de rellenos sanitarios: avances recientes(Universidad de Los Andes, 2001) Eugenio GiraldoItem type: Item , Use of electrodialysis as a vfa recovery process From acidogenic of msw synthetic leachates(Universidad de Los Andes, 2003) M.A. Bermeo; Aymer Maturana; Sandra L Estévez; Marlén Rodríguez; Eugenio GiraldoAn electrodialysis (ED) process was tested for volatile fatty acids (VFA) recovery from a simulated leachate of acidogenesis of municipal solid wastes (MSW). The effect of initial VFA concentration in leachate, applied voltage and flow rate on VFA removal efficiency were evaluated. Four different leachate compositions were examined at three different applied voltages and at three different flow rates. Higher removal levels were obtained at low VFA initial concentration, high voltages levels and high flow rates. ED process was showed higher removal efficiency with shorts chain acids, but VFA final concentration was directly related with initial concentration of each acid. After VFA recovery tests of chemical reaction with ethanol were carried out for ethyl esters production as gas oil additives. Results of these tests showed a transformation efficiency of 26%.
