Course Textbook:
Water and Wastewater Technology, 6th Edition, Mark J. Hammer and
Mark J. Hammer, Jr., Prentice Hall, 2007.
(ISBN: 978-0131745421).
Course Goals:
·
To introduce the student to the design process for water
transmission mains, distribution storage and pipe systems, and sanitary sewers;
·
To introduce the student to the principles and design aspects
of major drinking water treatment and municipal wastewater treatment processes
Course Outcomes:
·
Ability to apply the principles of conservation of mass and
energy to calculate flow rates, head loss, pumping and power requirements in
closed conduits.
·
Specific knowledge of the physical, chemical and
microbiological standards that must be met for drinking water and wastewater
treatment.
·
Proficiency at preliminary design of storage reservoirs to
meet fluctuating demands and equalize pressures.
·
Ability to formulate and solve mass balance problems for
various types of reactors (batch, completely mixed, plug flow) for both
conservative and non-conservative pollutants.
·
An understanding of the reasons for stability of colloidal
dispersions, the methods of destabilizing colloids and the chemical
requirements for coagulation.
·
General knowledge of the types of settling that occur in
clarifiers, including the use Stoke’s law to calculate settling velocity, and
the design of an ideal settling basin for particles with discrete
settling.
·
Working knowledge of particle removal mechanisms in filters,
and the ability to perform preliminary design calculations for a filter
including filter area and depth, initial head loss, and backwash frequency and
flow rate.
·
Working knowledge of the chemistry of disinfection and
by-product formation, including an ability to calculate the C·t for pathogen
inactivation and perform preliminary design calculations for chlorine contact
tanks.
·
Ability to use Manning’s equation to calculate discharge,
velocity, depth of flow for open channels and to describe the components and
design considerations for sanitary sewers, and to perform preliminary design
and layout of a sewer system.
·
A good knowledge of the major groups of microorganisms and
their role in wastewater treatment, includig the role of electron donors,
electron acceptors, carbon source, nutrients, and environmental conditions on
biological treatment processes.
·
Ability to describe the components of an activated-sludge
treatment process, calculate BOD loading, F/M ratio, HRT, SRT, and O2
utilization and sludge production rate for an A-S system and describe the
advantages/disadvantages of A-S variations.
·
Knowledge of attachment of microorganisms to surfaces, and the
components of a trickling filter treatment process, including the ability to perform
preliminary design calculations for trickling filter design.
Course Outcome
Measures and Assessment:
Measures and assessments of outcomes will be
made by periodic homework problem sets on the principles covered in class lectures
and reading assisgnments, two 1- hour mid-semester examinations, and one 2-hour
final examination to provide feedback on comprehension of lectures, problem
sets and reading assignments. Class
participation includes oral and electronic (PRS) responses to questions posed
by the instructor.
Problem
Sets 20 %
Class
participation 5%
Examination Schedule
The mid-term exams
will be given during special sessions outside of normal class time. They will be 75 to 90 minutes in duration,
starting at
Homework
A total of 8 to 10 problem sets will be
assigned. Most will be individual work,
but as many as 2 -3 may be assigned as group work. Problem sets are due at the beginning of the
class period on the date due – no credit given for late problem sets. Except for group assignments, submitted problem
set work must be done by each individual, however, studying in groups for productive
mutual learning is encouraged. Homeworks
must be neat, with final answers readily identifiable (e.g., boxed in).
Class Attendance:
You are being educated for a professional
degree and to enter a profession. You
are expected to attend all classes and arrive on time. Obtain prior clearance for planned
absences. Poor attendance or excessive
tardiness will negatively affect your grade.
