Denitrifying bacteria are immobilised in gel beads and
used in a stirred reactor for removal of nitrate from groundwater. At a nitrate
concentration of 3 g m -3, the conversion rate is 0.011 g s-1 m-3
catalyst. The effective diffusivity of nitrate in the gel is 1.5 × 10 -9
m 2 s-1, the beads are 6 mm in diameter, and the
liquid-solid mass-transfer coefficient is 10 -5 m s-1. Km
for the immobilised bacteria is approximately 25 g m -3. Calculate
the observable Thiele modulus with CAs = 1.9 g m -3
