4. A suspension of yeast cells is to be filtered at a constant filtration rate of 50 L/min. The suspension has a solid content of 70 kg/m3 of suspension and the yeast cells have a bulk density of 800 kg/m3. Laboratory tests indicate that the specific cake resistance is 40 m/kg and the viscosity of the filtrate is 2.9x10-3 kg/m.s. The filter has an area of 0.1 m2 and the medium offers negligible resistance. How long can the filtration rate...
The principle of filtration is based on the so-called Hagen-Poiseuille Equation (1c). (1c) 4 ao! where V = the volume of filtrate collected (m) t = filtration time (s) A = filter area (m²) P = total pressure across the system (Pa) m = weight of cake per unit volume of filtrate (kg m u = filtrate viscosity (Pas) a = cake-specific resistance r=resistance of the filter ) In a typical filtration experiment, a plot of t/V vs V is...
The following data was obtained from a constant pressure cake filtration experiment: Time (s) 5 10 20 30 V(t) (lit) 0.040 0.055 0.080 0.095 The following additional information is given: A = 0.1 ft2, Cs = 0.015 kg/1, ju= 1.1 centipoise, AP = 10 N/m2. a) Determine RM b) Determine the specific cake resistance
Solution please
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...
