A proof pilot study consisting of MF, RO and constructed wetlands systems was conducted during the design of the City of Oxnard's 94.6 ML/d (25 mgd) Advanced Water Purification Facility. This study was intended to evaluate unit performance for wastewater with high membrane fouling potential to achieve a finished water quality suitable for groundwater recharge and irrigation. After some modifications the MF and RO units met all the full-scale design and operational criteria. The RO treatment achieved removal of key constituents below the target levels. The RO permeate contained TOC, TN, TDS and chloride concentrations less than target levels of 0.5, 5, 500 and 250 mg/L, respectively. The RO unit reduced NDMA concentration by approximately 50 percent and 1,4-dioxane by approximately 80 percent. The constructed wetland plant Bullrush was found to tolerate the high levels of TDS and provided significant mass removal of nitrogen and other constituents in the RO concentrate.
