1993-94 Catalog Data:Introduction to water treatment and water pollution and the analysis and design of selected treatment processes.Prerequisites: CE 256. Corequisites: CE 331 3 credits.

Text: Environmental Engineering. Peavy, H. S., D. R. Rowe, and G. Tchobanoglous, McGraw-Hill, New York, NY, 1985.

Coordinator: Adrian T. Hanson, Associate Professor of Civil Engineering

Goals: This course is designed to teach the civil engineering student the fundamental engineering design principles of water treatment (physical-chemical treatment), wastewater treatment (biological treatment), and stormwater and municipal wastewater collection system design. Design problems are incorporated into the course as applications of these principles.

Prerequisites by Topic:

• 1. Fundamentals of chemical equilibrium
• 2. Fundamentals of acid-base chemistry
• 3. Fundamentals of precipitation chemistry
• 4. Hydraulics of open channel flow
• 5. Hydraulics of closed pipe flow

Topics:

• 1. Introduction to water treatment
• 2. Standards, design guidelines and typical process flow schematics for surface and groundwater sources.
• 3.Design loadings (population projections)
• 4.Flow Measurement
• 5.Type-1 settling
• 6.Type-2 settling
• 7.Design of Sedimentation Basins
• 8.Coagulation and Rapid Mixing
• 9.Flocculation (2 periods)
• 10.Filtration overview
• 11.Headloss through a filter
• 12.Backwashing hydraulics
• 13.Filter components
• 14.Types of filters and filter operation
• 15.Clear wells, distribution system, and storage
• 16.Permits, design guidelines and typical process flow schematics for wastewater treatment
• 17.Primary treatment; screening, grit removal, and sedimentation
• 18.Activated sludge (suspended growth) overview (3 periods)
• 19.Aerated Pond Systems, and Stabilization Ponds
• 20.Fixed film processes overview
• 21.Trickling filters (2 periods)
• 22.Final Clarifiers
• 23.Sludge Handling (2 periods)
• 24.On-site disposal {septic tanks, mounds, drainfields, etc.} (3 periods)
• 25.Design of sanitary sewer systems (4 periods)
• 26.Design of Storm Sewers (Rational Meth.)

Computer Usage: Students are required to use spreadsheets on four problem solutions. Students are given a number of design problems that are, in part, appropriate for computer solution. These are: type I settling, filter backwash calculations, clean bed headloss in a filter, and the design of a gravity sewer line.

Laboratory Projects: None.
