In a batch production of penicillin, 40 m³ capacity of the plant, sterile air is required to be supplied. The bioreactor requires 1 vvm (volume of air/volume of broth. min). The incoming air contains 3000 cells/m³of air, for 100 hours operation. Calculate the depth of filter if the penetration of bacteria is 1 in 1 million.
