| contents | Treatment of fue diesel with a permeable reactive barrier technology SANTIAGO ALONSO CARDONA GALLO Ingeniería nutrients Fuel diesel biodegradation permeable reactive barriers The objective of this investigation is to study the treatment of the diesel production of Mexicancontent in water with a system of permeable reactive barriers in laboratory (seven columns). An agricultural soil(ASo) was used as half reagent medium. It was applied peroxide of hydrogen to 50% industrial as source ofoxygen and nitrogen in urea to 46% as nutrient. This characterized the reagent medium with the main parametersof interest (humidity, organic matter, pH, total nitrogen, available phosphorus, classification of the soil, volatilesuspended solids, electric conductivity, real and apparent density, porosity, texture, color, hydraulic conductivity,field capacity and density of bacteria. The kinetic of degradation and the capacity of adsorption of the diesel wasdetermined in the reagent medium by batches tests. The permeable reactive barriers were designed with thekinetic results obtained in the reactors by batch. The columns had 30 cm of length and 10 cm of diameter. Thekinetics was determined during 18 days and the columns were run during 70 days where they presented removalsup of 80 % in columns. An initial concentration of diesel of 15,000 mg/L was used. For the modeling of theadsorption the Langmuir equation was applied. For the supply of nutrients and oxygen the pattern proposed byMcCarty and the half equation for diesel proposed by Jackson was applied. A velocity of degradation in thereagent medium of 0.0908 d-1 a coefficient of distribution of the diesel in the reagent medium of 0.8 ml/L, acapacity of adsorption of diesel in the medium reagent of 13.50 mg/L and a factor of retard of 3.69 in the soil ispresented 2007 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49615336 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.153 Vol.74 |
