“…Bacteria transport, however, was unaffected by changes in pH in the range of 5.5 < pH < 7.0 in both systems (see Table V). The influence of ionic strength on transport parameters of other microorganisms have also been reported by Hilbert (1992), Logan et al (1993), and Kinoshita et al (1993) with results similar to the findings of Jewett et al(1995).…”

“…Value of a has also been estimated on 40-mm glass beads using radiolabeled P. fluorescens P17 by Gross et al (1995). The bacterial collision efficiency values, a's, reported by these investigators are in direct agreement with the results of Jewett et al (1995).…”

“…Differences in surface particle chemistry or collector surface roughness not directly included in the theoretical model are incorporated into the collision efficiency (␣), which is defined as the probability that a particle attaches to a surface based on the frequency of collisions. Mini-column tests have proven to be an effective and rapid alternative to breakthrough column tests for measuring bacterial collision efficiencies (3,5,10,19). Retention or total breakthrough can be measured by incorporating a radiolabel into the bacterium, which allows rapid calculation of the collision efficiency.…”

“…Retention or total breakthrough can be measured by incorporating a radiolabel into the bacterium, which allows rapid calculation of the collision efficiency. To examine bacterial retention, a small slice of medium is removed from the top of the bed and analyzed by scintillation counting (10). However, a radiolabel-based method is not practical for GAC as the label sorption to the carbon does not permit subsequent measurement of bacterial retention (26).…”
