Water and Wastewater Technology, 6th Edition, Mark J. Hammer and Mark J. Hammer, Jr., Prentice Hall, 2007. (ISBN: 978-0131745421).
· 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
· 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%
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 . Tentative dates are March 10th and April 15th. The final exam will be during the scheduled final exam period.
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).
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.
