- A process has an input as the flow q gal/min, and an output temperature T Fahrenheit. Initially, the process has been operating for long time at input flow 610 gal/min and output temperature 180 Fahrenheit.
An operator introduces a step change in the flow rate (q) to a given process at 4:00 O’clock A.M. He changed the flow from 610 gal/min to 650 gal/min. The effect of the input change resulted in a change in the output. The first change in the temperature occurred at 4:20 O’clock A.M. Then the temperature increased fast, and then slowly reached steady-state value of 220 Fahrenheit . The operator noticed that there is no change in the output after 4:44 O’clock A.M.
Given the above data,
find the first-order (possibly with time-delay) approximation of the transfer function from the flow to the temperature. Find for the model.
and simulate the first order function and response by Matlab

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...
