Abstract:A two-year study of the impact system scale has on short-term fouling rates and long-term membrane performance was conducted. Four system scales; bench, module, cassette and plant were used. Bench and module scale systems were found to be useful for evaluation of alternative membrane designs and operational parameters. Plant scale testing was found to be required for long-term performance validation. Monitoring of mixed liquor filterability at different system scales using colloidal TOC and time-to-filter revealed a tendency for smaller systems to react more rapidly and drastically to sudden process changes.
