Monod Assignment
All work is to be completed
individually. No collaboration or
discussion is allowed.
Problem
#1
Completely mixed aeration systems are
sometimes modeled using the Monod equation.
1. Read sections 3-12 and 11-7 in your
textbook.
2. Work example 11-9 by hand, showing
all your work.
3. Work the same example by placing all
the equations on a spreadsheet.
4. Use your spreadsheet to vary the
values for Y and kd (Table
11-6 shows typical ranges). Plot the
growth yield ratio (x-axis) versus the tank volume (y-axis) keeping the decay
coefficient constant at 0.06 per day.
Plot the decay coefficient (x-axis) versus the tank volume (y-axis)
keeping the growth yield ratio constant at 0.6.
4.
Provide a discussion paragraph answering the following. What do the constants Y and kd
represent and how does varying those constants change the required tank
volume?
