Assignment 3

Wastewater Treatment Unit Process Worksheet

Complete the following questions. Respond with a 100- to 150-word answer to each question.

• Describe the wastewater treatment technologies in a conventional municipal wastewater treatment plant. Specifically discuss flow, biochemical oxygen demand (BOD) removal, solids removal and handling, and effluent quality.

• Compare the wastewater treatment technologies described in the preceding question to technologies that would be used for a smaller flow system. How are flows, BOD removal, solids removal and handling, and effluent quality different for smaller systems?

• Describe the treatment technologies associated with advanced treatment that is beyond conventional treatment. Which pollutants are being addressed with advanced treatment? Why?

• Describe the major equipment associated with preliminary and primary treatment processes. What is the purpose of each piece of equipment for pollutant removal? Which solids residuals are generated?

• Describe the major equipment associated with secondary and disinfection treatment processes. What is the purpose of each piece of equipment for pollutant removal? Which solids residuals are generated?

• Describe the major equipment associated with advanced treatment processes. What is the purpose of each piece of equipment for pollutant removal? Which solids residuals are generated?

• Consider the solids residuals generated by the unit processes described in the three preceding questions. Describe residual treatment, handling, and disposal options. Which regulations apply to the final biosolids disposal?

• How do the concepts of asset management apply to wastewater treatment technologies? Specifically, discuss equipment maintenance, equipment failure, energy efficiency, emergency reserves, and standard practices. How do asset management concepts save customers money in the long run, in spite of potentially higher costs in the short term?
