Formation of Disinfection Byproducts by Chlorination of Secondary Wastewater Effluent and Their Removal With Water Reuse Technologies
Abstract:The Miami-Dade Water and Sewer Department is implementing a strategy to replenish its drinking water aquifer with secondary wastewater treatment plant effluent treated with advanced water treatment processes. A pilot plant of the proposed South District Water Reclamation Facility was constructed and operated to test the process train consisting of deep-bed sand filters, membrane filtration, reverse osmosis, ion exchange, and UV-advanced oxidation. Among the microconstituent compounds tested were disinfection byproducts, with N-Nitrosodimethylamine (NDMA) being of particular concern. The high-level disinfection process, deep bed sand filtration followed by chlorination, did create disinfection byproducts in the form of NDMA, total trihalomethanes (TTHMs) and Haloacetic acids (HAA5). The downstream technologies were able to remove them, but NDMA levels were not reduced to below the treatment goal. This will be addressed in full-scale design of the UV-advanced oxidation system, the primary mechanism for NDMA removal.
