    Abstract

    Productivity and water quality from the Roy W. Likens membrane facility in Palm Coast, Fla., were accurately simulated by three membrane pilot plants in a four-month field investigation using various sizes of a film membrane manufactured by the same company and operated under the same conditions. All plants used the same source water, groundwater that is moderately hard (330 mg/L as CaCO3) and highly organic (11 mg/L non-purgeable dissolved organic carbon, 336 trihalomethane formation potential [THMFP], 227 mu g/L haloacetic acid formation potential [HAAFP]). All pilot units were built and operated according to standards in the Information Collection Rule (ICR). The average finished water quality for all membrane plants was 0.4 mg/L total organic carbon as C, 35 mu g/L THMFP, and 28 HAAFP. For the full scale plant, membrane productivity over time than did a zero-order direct mass transfer model, although both models produced statistically significant results. These results demonstrated that full-scale plant performance could be accurately scaled up from single-element or multistage pilot plants as specified in the ICR protocol.
