You want to invest in a larger processing filtration facility. In the current facility, 12 m3 of filtrate are produced and in the new one you should get 60 m3 of filtrate. You want to find out if the old existing filter apparatus could be used in the new facility. Thus, you want to compare the performance of the existing old' plate and frame filter with a 'new' one you intend to buy. Both are to be used to process an aqueous slurry (T 25°C, viscosity-0.881 mPa.s) in the constant pressure mode. The constant pressure (-AP) for both systems would be 450 kPa. In order to compare the systems you determined the following experimental data for both the old and new system. The slurry concentration is 15 kg/m3 in both cases. The filter area for the experiments is 0.05 m2 for both the new filter and the old filter OLD NEW Time (s) Vitrate (m2) Time (s) Vniltrate (m3) 4.0 6.474E-04 4.6 1.300E-039.9 1.951E-03 17.0 2.600E-03 25.7 3.247E-03 36.31.108E-03 3.903E-03 48.2 1.446E-03 4.558E-03 61.7 5.205E-03 77.0 2.224E-03 5.853E-03 93.5 6.512E-03 112.2 3.128E-03 1.499E-04 3.212E-04 5.415E-04 8.022E-04 16.6 25.1 35.4 60.3 1.817E-03 91.4 109.7 2.654E-03 1. Calculate the resistance of the filter medium (Rm in m) as well as the specific cake resistance (a in m/kg) for both the old and new filter systems. (50 points) 2. The old filter press has a total filter area of 30 m2 The new filter press has a total filter area of 35 m2. For the actual process you can assume the same filter cake properties and filter cloth, as well as the same constant pressure (-AP) as in the experiments in the lab. How long would it take to recover 60 m of filtrate for the new and old filter (tfitlernew, tfilter old)? (50 points) Note: Please use a computer to plot your graph.
