E – 1415 Introduction to Water Pollution

Description

Introduction:
• Water Pollutants and Their Sources
• Water Pollution in Rivers
– Total Maximum Daily Load (TMDL)
– Effect of Oxygen-Demanding Wastes on Rivers
– Biochemical Oxygen Demand (BOD)

Water Pollution in Rivers:
– Graphical Determination of BOD Constants
– Laboratory Measurement of BOD
– DO Sag Curve
– Effects of Nutrients on Water Quality in Rivers

• Identify water pollutants and their sources;
• Define TMDL, BOD, & COD;
• Model BOD and calculate BOD5 and BODu
• Determine BOD rate constants graphically;
• Develop DO Sag Curve (Model); and
• Explain the effects of nutrients on water quality in rivers.
