The density of all streamsis 920 kg/m3. At the nominal steady state, the flow rates of streams 1 and 2 are 950 and 425 kg/min,respectively, the liquid level in the tank is 1.3 m, the incoming mass fractions are x1 = 0.27, x2 = 0.54. Noticethe overflow line, indicating that the liquid level remains constant (i.e. any change in total inlet flow ratetranslates immediately to the same change in the outlet flow rate). You may assume the stream 1 flowrate andthe stream 2 composition are both constant. Use minutes as the time unit throughout this problem.

A toxic organic solute (species A) diffuses into the biofilm and is degraded to harmless products by the cells within the biofilm. We want to treat 0.2 m3 per hour of wastewater containing 0.14 mole/m of the toxic substance phenol using a system consisting of biofilms on rotating disk as shown below. thickness of the biofilm is 1 mm and we are interested to reduce the phenol concentration in the outlet stream to 0.025 mole/m3. The rate of disappearance of phenol (species A) within the biofilm is described by the following equation rA = - KICA Where k1 = 0.0024 s-1 The diffusivity of phenol in the biofilm at the process temperature of 25°C is 2.0x10 10 m2/s.
