Title

Nf Performance At Full And Pilot Scale

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 μg/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 μg/L THMFP, and 28 HAAFP. For the full-scale plant, membrane productivity decreased by 50 percent during five years. A second-order resistance model more accurately described 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.
