요약 | Emerging contaminants have been identified in detectable quantities in wastewater effluents around the world. These emerging contaminants include pharmaceuticals, personal care products, industrial and household chemicals, as well as endocrine disrupting compounds that are not removed through traditional wastewater treatment processes. A small-scale novel bioreactor was designed and optimized to remove these contaminants from tertiary treated wastewater effluent from a water reclamation plant in Tucson, Arizona. More specifically, this bioreactor was designed to treat 15 liters of effluent by circulating it through a hydroponic media bed bioreactor. Four hydroponic media- 25.4-mm lava rock, 12.7-mm (small) fractured rock, 25.4-mm (large) fractured rock and 12.0-mm expanded clay pebbles (LECA)-underwent hydrodynamic tests to determine which provided optimal flow conditions for maximizing dispersion and mixing within the bioreactor. Tracer tests were performed for each media with a sodium chloride tracer and used to determine the mean residence times (MRT) and vessel dispersion numbers at two different flow rates (6.9 and 9.7 L min-1) and two water levels (11.8-12.8 and 20-20.8 cm). In the low water level treatments, expanded clay had a 16-29% longer MRT (148.7짹8.0 s) than the other media (small rock - 128.1짹17.3 s |
요약 | Future research should focus on the specific pathways of contaminant removal within a hydroponic media bed bioreactor and how those pathways can be optimized for maximum removal of emerging contaminants. |
