#Section 5: Bioprocess Engineering and Process Biotechnology

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
