A 15-m 3 chemostat is operated with dilution rate 0.1 h-1. A continuous steriliser with steam injection and flash cooling delivers sterilized medium to the fermenter. Medium in the holding section of the steriliser is maintained at 130⁰C The concentration of contaminants in the raw medium is 105 ml-l; an acceptable contamination risk is one organism every 3 months. The Arrhenius constant and activation energy for thermal death are estimated to be 7.5 × 1039 h-1 and 288.5 kJ gmol- 1, respectively. The steriliser pipe inner diameter is 12 cm. At 130⁰C the liquid density is 1000 kg m- 3 and the viscosity is 4 kg m- 1 h- 1. Assuming perfect plug flow, determine the length of the holding section. __________________
