APERÇU

After participating in this course, you will be able to:

• Characterize wastewater based on its strength and concentrations of contaminants
• Recognize the types of wastewater contaminants, the conventional processes used to remove them, and the types of treatment equipment required for their removal
• Apply the principles and practices of conventional wastewater treatment systems to the removal of suspended solids and colloids, organic matter, nitrogen, and phosphorus
• Recognize the operation principles of membrane processes in advanced wastewater treatment systems
• Develop a better understanding of conventional and advanced treatment processes for wastewater reclamation and reuse

Description:
This course discusses the principles and practices of wastewater treatment, water recovery and reuse. It addresses wastewater characterization as well as the operation principles and applications of biological and physical-chemical treatment processes used in the removal of organic and inorganic contaminants from wastewater.

These processes include sedimentation, coagulation-flocculation, activated sludge, trickling filters, rotating biological contactors, lagoons, disinfection and membrane processes. The application of conventional and advanced treatment processes in wastewater reclamation and reuse will be discussed, and case studies will be presented.

Course Outline:

• Wastewater characterization
• Wastewater treatment stages: preliminary, primary, secondary and tertiary treatment
• Coagulation-flocculation processes
• Fundamental aspects of biological processes and microbial kinetics
• Biological treatment technologies: applications and operation principles
