408. Treatment Plant Design. Design and upgrading of a wastewater treatment plant; process sizing and plant layout, clarifier and plant hydraulics; diffused aeration system design with energy requirements; overall plant mass balances and cost analysis; structural considerations and hydraulic profiles; water treatment plant process sizing, coagulation and filtration design and hydraulic profiles. Two lectures, one two-hour problem period. Fall  (Cr.3) 

Prerequisites: CIVL 304, ENGS303. Evaluation of water quality; Fluid  mechanics: open channel hydraulics; Waste strength characterization; Waste treatment; Water treatment.

Course Goals:

1. This is a hands-on capstone course. Its purpose is to provide students with the ability to perform integrated process and detailed design calculations for major wastewater treatment systems using knowledge from this and prior courses. The students prepare their design using a team effort simulating a real-world environment.

Course Objectives:

The student will be able to

• To develop students ability to incorporate engineering standards and realistic constraints in a major design experience.

• To develop the students ability to research the various design regulations to be followed during a design phase of a project.

• To develop the students ability to design the treatment process for a municipal waste water treatment plant.

• To develop students understanding on how to perform an economic analysis on a design project.

• To develop students understanding on how to incorporate health and safety constraints related to a design project.

• To develop students understanding on how ethical, social, and political issues design projects.

• To provide the student with an experience of working on a multi disciplinary team.

• To develop the students ability to prepare a team based design report.

• To develop the students ability to make a public presentation.

• To provide the student with a insight into the basic professional practice issues related with project procurement and construction.
