PERMEABLE BIOSORBENT BARRIER FOR WASTEWATER REMEDIATION
Silva, B., E. Tuuguu, F. Costa, V. Rocha1, A. Lago, and T. Tavares.
Environmental Processes 4(Suppl 1):195-206(2017)
In a study of Cr(III) removal from surface water by a permeable barrier, the adsorption capacity of 13X zeolite and vermiculite was investigated at different sorbent dosages, pH, and initial Cr(III) concentration in a lab-scale reactor set up to simulate a permeable barrier. 13X zeolite had the better performance for Cr removal in the permeable barrier assays, achieving 96% total Cr removal and a global uptake of 2.49 mg/g. Neither barrier had reached Cr saturation after 13 days of operation. Additionally, a fungal isolate identified as belonging to Alternaria alternate was obtained from sediment samples and selected from enriched Luria-Bertani medium. After 50 h of cellular growth the fungal isolate was able to remove 78.2% and 47.9% of Cr(III) at initial concentrations of 50 mg/L and 100 mg/L, respectively. https://repositorium.sdum.uminho.pt/bitstream/1822/47024/1/document_46729_1.pdf
