Design and upgrade 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 costs analysis; hydraulic profile; water treatment plant process sizing, coagulation and filtration design and hydraulic profile. Two lectures and one two hour design period. Three credits. Prerequisites: ENVL 307

  Textbook:

Wastewater Treatment Plants - Planning, Design, and Operation, Syed R. Qasim, 2nd Ed., Technomic Publishing Co., Inc., Lancaster, Basel, 1999

Recommended Standards for Wastewater Facilities, Great Lakes - Upper Mississippi River Board of State and Provincial Public Health and Environmental Managers, (10 State Standards), Health Education Services, Albany, NY, 1997.

  Goals:

To introduce the principles of treatment plant design with the specific design of a municipal wastewater treatment plant.  This design includes the use of Federal and Ten State Standards.  In addition, students are taught principles of plant layout, operation, selection and purchasing of equipment, energy requirements, and cost analysis..

  Objectives:

1.   To apply statistical principles to the analysis of existing historical plant data to determine design wastewater characteristics.

2.   To apply the principles of fluid mechanics and hydraulics to design pump stations and to determine hydraulic profiles in treatment plants.

3.   To apply the principles learned in the ENVL 506 process course to the design of BNR processes.

4.   To utilize the latest computer design programs for various aspects of plant design.

5.   To get an appreciation for the practical current-day design aspects of wastewater systems and the presentation of a design with plan and profile views, incorporating a cost analysis, in an Engineering report.

6.   To continue to ignite the student's enthusiasm for their future profession in environmental engineering.
