WTRQ 2270 - Solids & Hazardous Waste


Credit hours: 3

Prerequisites: WTRQ 2210 - Wastewater Treatment I   

Course Description:
This course focuses on removing and managing solids from wastewater effluents.  Also discussed are wastewater reclamation and treatment methods specific to non-municipal wastewater effluents. This course includes required field experience at local wastewater treatment facilities.

Student Learning Outcomes:
Students will be able to:

  1. Relate broad concepts, principles, and theory pertaining to solid waste production and processing in wastewater treatment systems. 
  2. Explain generalized concepts of coagulation and flocculation in relation to solid waste production in wastewater treatment systems and describe advantages and disadvantages of alum, ferric hydroxide, lime, and polyelectrolytes in sludge production. 
  3. Apply standard computational methods for calculating activated sludge return rates and wasting rates in wastewater treatment systems. 
  4. Summarize strategies for enhanced biological control in activated sludge production and explain the importance of nitrogen and phosphorus removal in wastewater treatment. 
  5. Compare and contrast similarities and differences among gravitational settling, gravity filtration, and inert-media filtration methods for processing solids in wastewater treatment systems. 
  6. Describe and compare methods for removing solids from secondary effluents in wastewater treatment systems. 
  7. Explain suitable operational responses for dealing with deviations in influent quantity and quality in wastewater treatment systems. 
  8. Describe odor sources and solutions to odor problems at wastewater treatment facilities.
  9. Explain the rationale for using pure oxygen in activated sludge processes, and summarize differences between pressure-swing adsorption and cryogenic methods for extracting oxygen from air.

  10. 10. Differentiate between primary sludge and secondary sludge in wastewater treatment operations, and describe processes used to manage these two sludge types.

  11. Summarize methods and operational processes for thickening and dewatering sludge from wastewater treatment systems.

  12. Summarize methods for sludge disposal, and describe methods used for sludge application in beneficial reuse activities.
