Introduction To
Wastewater Treatment
Problem 1-1
Instructors Note: The first six problems are designed to illustrate the
application of the mass balance principle using examples from hydraulics with
which the students should be familiar.
Problem Statement - See Text, Page 53
Solution
1. Write A Materials Balance On The Water In The
Tank Accumulation = Inflow – Outflow +
Generation
Dv Dh
= A = Q –Q + 0
In Out
Dt Dt
2. Substitute Given Values For Variable Items And Solve For H
Dh T 3
A = 0.2 M3
/ S – 0.2 1 − Cos
43,200
M /S
Dt
A = 1000 M2
T
3. Dh = 2 X10−4 Cos Dt
43,200
Integrating The Above Expression Yields:
(43,200) (2 X10−4) T
H − Ho = Sin
43,200
4. Determine H As A Function Of Time For A 24 Hour Cycle
