It is required to provide a 20-m^3 fermenter with air at a rate of 10 m^3 min ^-I for a fermentation lasting 100 hours. From an investigation of the filter material to be used, the optimum linear air velocity was shown to be 0.15 m sec^-I, at which the value of K was 1.535 cm^-I. calculate The dimensions (radius and depth) of the filter? The air in the fermentation plant contained approximately 200 micro-organisms m^-3. The acceptable degree of contamination is one in a thousand.
