Course Description: Catalog Description: Fundamentals and design of sustainable systems for water supply, domestic and industrial wastewater treatment, soil and groundwater remediation; semesterlong design projects; energy and resource recovery. The goal of this course is to provide students with the fundamental understanding of water and wastewater engineering, as well as the methods involved in quantitative sustainable design and operation of treatment processes. Students will learn physical, chemical and biological principles governing the design of conventional and emerging treatment technologies, including coagulation-flocculation-sedimentation, filtration, ion exchange, disinfection, activated sludge process, biofilm and anaerobic treatment etc. This course also encourages students to integrate sustainability strategies, such as greenhouse mitigation, energy saving and resource recovery into the design and practice of water and wastewater treatment. Course Objectives: At the successful completion of this course students will: 1. Understand the physical, chemical and biological principles governing typical water and wastewater treatment processes. 2. Have the ability to design either a complete water treatment or wastewater treatment process to meet a water quality target. 3. Have the ability to suggest process design and diagnose common operating problems in the treatment of water, wastewater and biosolids. 4. Understand sustainability challenges in water/wastewater engineering in relation to energy, resource and water reuse. Design Project: The design project will focus on using simulation packages such as SuperPro Designer ® (Intelligen, Inc.) and BioWinTM (EnviroSimAssociates), to mediate water/wastewater treatment modeling and design. Students are encouraged to incorporate energy recovery, nutrient recovery or water reclamation units in conventional treatment processes. A group report with clearly stated objectives, design parameters, simulation results and sustainability assessment are required by the end of the course. Grading Policy: Homework: 20% (8 homework assignments and 1 group presentation) Classroom participation and random quizzes: 10% Mid-term exam: 25% (closed-book, 1h in-class) Final exam: 25% (take-home) Design Project: 20% (1 final report) 1. Please submit your homework assignments in class (Fridays), to the instructor’s mailbox in Votey 103, or email a scanned copy to the TA before the due time. 2. Homework assignments will be graded and returned 1 week after the due date in class. Answers to homework assignments can be found on Blackboard on the same day. 3. Late homework submission: max 5 late days/semester with maximum allocation of 2 late days/assignment are allowed without penalty. The penalty for “true” late assignment (>5 late days/semester or >2 late days/assignment) is 1% of your FINAL grade per late day. 4.
