CEGR 338 - ENVIRONMENTAL ENGINEERING I Homework #1 Based on Chapter 1 - Mines, R.O., Lackey, L.W. (2009). Introduction to Environmental Engineering. Prentice Hall, Upper Saddle River, NJ. Due: Friday 6/13, submit to BlackBoard Instructions: Be mindful of course rules. Properly cite and provide references of any websites you may have used for answering questions. For Exercises 1 through 4, use the textbook or internet to perform a Google search for help in answering the questions. If necessary, seek out a professor or environmental engineer to discuss the topics presented. Then, prepare at least a written paragraph for each topic. Discuss the role each topic plays in environmental engineering. For these answers, you may include comments on the types of problems that an engineer may confront and how to solve these problems for each topic. 1. How are the principles from microbiology used in the design of wastewater treatment processes? 2. Environmental engineers and scientists have reported that global warming may be a real problem. List and discuss the major causes and the air pollutants that are associated with this phenomenon. 3. Environmental engineers are responsible for designing water treatment plants that provide safe, potable drinking water to the public. What chemical principles are used for removing pollutants from water? Give some examples of unit processes that are used for treating water. 4. Hydrology is another area in which environmental engineers are highly involved. During storm events, rain that falls to the surface either percolates into the soil to replenish ground water supplies or becomes surface runoff. Stormwater runoff from impervious areas in cities or from agricultural areas contributes large volumes of water and is of poor quality, due to pollutant entrapment and dissolution. List and discuss some of the contaminants that might be found in urban stormwater runoff versus agricultural runoff. 5. Many environmentalists promote the idea of recycling solids wastes. Collection, separation, and recycling systems are often designed by environmental engineers. List at least 4 advantages and 4 disadvantages of recycling metals, glass, and paper discarded in solid wastes. 6. Based on the 2017 ASCE Infrastructure Report Card, what are the grades for America’s Drinking Water and Wastewater infrastructure? How much money is needed for each sector to improve the current condition and meet future demands? Name 3 challenges that this will present to Environmental Engineers in the near future. 7. A long, rectangular settling basin is used for removing suspended solids during water treatment. The length-to-width ratio of the basin is 4:1 and the width-to-depth ratio of the basin is 1:1. Determine the basin’s volume in cubic feet if its depth is 30 feet (Show work by typing or include image/scan of calculations). 8. A 35-meter-diameter circular tank that is 12 meters deep is used for storing liquid sodium hydroxide solution at a wastewater treatment plant. Determine the tank’s cross-sectional area in square meters and its circumference in meters. (Show work by typing or include image/scan of calculations).
