COURSE OBJECTIVE

The purpose of this course is to prepare you for professional practice as an environmental engineer. This course will primarily focus on water and wastewater treatment. However, the course emphasis on the integration of fundamental concepts will allow the student to extrapolate the lessons learned in the course to other specialties in environmental engineering such as hazardous waste remediation and industrial waste treatment. At the completion of the course you will be familiar with1) major unit processes used to treat water and wastewater, and 2) the design process with respect to environmental engineering projects. You will also gain experience in skills critical to practicing engineers such as working productively in a group and communication skills. During the course you will get a chance to tour local facilities that will provide you with a real world view of environmental engineering.

EXPECTED LEARNING OUTCOMES

At the completion of this course you will be able to:

  1. design water and wastewater treatment systems (ABET outcome A, C, E and K)
  2. solve mass material balances for environmental systems (ABET outcome E)
  3. recommend appropriate unit processes for water and wastewater treatment(ABET outcome E)
  4. understand contemporary environmental engineering issues (ABET outcome J)

GRADING POLICY

Weighted average grades will be calculated based on the following distribution:

Homework assignments / 35%
Midterm exam / 15%
Final Exam
Design Project Report and Presentation / 15%
35%

Final grades will be based on A (93-100%), A- (90-92%), B+ (88-89%), B (83-87%), B- (80-82%), C+ (78-79%), C (73-77%), C- (70-72%), D+ (68-69%), D (62-67%), D- (60-62%), F (< 60%). The instructor reserves the right to curve up, e.g., upwards to a higher grade than earned on this scale. A one page, 8.5"X11" sized, double sided page of handwrittennotes is allowed for exams. Assignments are due at the beginning of the assigned period.Late assignments will not be accepted. Peer evaluations will be used in scaling the Design Project grades for each member of the design team.

ATTENDANCE POLICY

You are expected to attend all classes.If you have a specific problem with attendance, notify the instructor prior to class, unless the emergency is such that this is not possible. Consistent with University guidelines, students absent from regularly scheduled examinations because of authorized University activities will have the opportunity to take them at an alternate time.Make up exams for absences due to other reasons will be at the discretion of the instructor.

OFFICE HOURS AND RESPONSE POLICY

I have scheduled office hours T and TH from 2 PM to 3 PM. I keep an open door policy and am happy to discuss class issues with students when in the office. Occasionally, when I am working on a deadline I will ask you to come back later during office hours, but this is typically an exception. I will respond to both emails and phone calls within 24 hours. However, I do my best to respond to student questions via email within a few hours of receipt, especially during business hours. Keep in mind I run my academic office similar to a consulting engineers office (time is money). Therefore, as professionals you should prepare your questions in advance so as to not waste my time or your time if you come in during non-standard office hours.

PLAGARISM AND ACADEMIC MISCONDUCT STATEMENT

Don’t do it! Students found engaging in plagiarism, cheating or forgery during any assignment, homework assignment, report or test will be subject to the conduct code policies of the University that can be found on-line at

HOMEWORK

Homework assignments are an integral part of the learning experience and will be carefully graded. As practicing engineers your work must be reviewed by many other engineers, therefore it needs to document your work thoroughly, logically and include all necessary information. Homework assignments not including problem setup or formulation will be returned with a 0 grade. A good homework solution will feature the following elements:

  1. Problem setup: All given information, as well as the values of additional constants (and their sources), should be listed. A sketch or diagram should be provided where appropriate. A brief statement of the problem objective should be included.
  2. Equations: The governing equations relevant to the solution of the problem should be written in algebraic form BEFORE substituting any numbers. If the equation must be derived, show all work. All relevant chemical reactions should be written and balanced.
  3. Assumptions: List explicitly any assumptions necessary to solve the problem.If the equation or value is taken from a reference such as the textbook or class notes, the equation number and reference should be noted.
  4. Solution: Present all work in a manner than can be understood by an engineering colleague. If the solution involves a programmable calculator spreadsheet or graphical technique, briefly describe the logic behind your solution approach.
  5. Answers: Clearly indicate answers (e.g., box, underline, circle, or highlight). Include both the correct number of significant figures and the relevant units for each answer.
