A single isothermal CSTR has the following elementary reactions. Case I: AB Case II: A B...
In a CSTR, reaction A→B occurs with rate constant kmol/s. The feed flow rate is Fi liter/s and the product flow rate is F liter/s. F is fixed (a pump is being used to maintain a constant product flow rate), whereas Fi is subject to changes. Therefore, the volume of solution in the reactor V is not necessarily constant. The concentration of A in the feed and product stream are CAi mol/liter and CA mol/liter, respectively. (a) (40 marks) derive...
QUESTION 2: Design of Multiple Reactors: 30 marks B +C was a a) An elementary reaction A reaction A B +C was carried out in a reactor system using an ideal STR followed by an ideal PER Isothermany. The rate constant is k = 0.4 min ". The volumetric flow rate is 20 L/min. The concentration of A in the feed is 5 moles/L. 1. Calculate the volume of the CSTR necessary to achieve a conversion of 50%. (7 marks)...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
