| dc.description | This paper presents a study to evaluate Rice Husk Ash adsorption potential in groundwater contaminated by BTEX (benzene, toluene, ethylbenzene and xylene) and TPH (total petroleum hydrocarbons). The methodology used in this research involved characterization of Porto Alegre/Brazil groundwater, characterization of adsorbents (AC and RHA) and laboratory and pilot scale assays (use of remediation system composed by: vacuum suction, aeration and adsorption filter). The results show high concentration and variability of BTEX and TPH in the groundwater studied. For benzene parameter, for example, it was obtained average concentration of 46.5 µg/L. According to the pilot scale study, it was observed decreases in TPH and BTEX ranging from 57.69% to 96.71% at suction system and 96.71% - 99.99% after adsorption mixed filter (50% RHA and 50% AC). The statistical tests ANOVA and Tuckey used here confirm, with a 95% confidence level, that the results obtained from the use of adsorption filter are significant. That is indicative of the importance of this treatment in order to guarantee process efficiency as well as confirm Rice Husk Ash functionality as adsorbent in adsorption filters applied to groundwater contaminated by hydrocarbons. | en-US |
