(b) Define concentration polarization and polarization modulus. How is polarization modulus mathematically related to filtration flux? If bacterial cell debris has G t = 54 x 106 sec, what centrifuge speed is needed to effect a full sedimentation in two hours? (centrifuge having bowl diameter of 10 cm) (4 + 2) + 6 = 12 What are the different methods of cell lysis? Discuss in detail. In Streptomyces filtration from an erythromycin broth using a test filter, we find the following data: 2. (a) 3. (a) (b) Filtration time, sec Volume of filtrate, L 5 10 20 0.040 0.055 0.080 The filter leaf has a total area of 0.009m² and the filtrate has a viscosity of 1.1 cP. The pressure drop is 0.51m of mercury and the feed contains 0.015 kg dry cake per liter. Determine the specific cake resistance a and the medium resistance RM. 30 0.095 6 + 6 = 12
