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.

Who Should Attend
Facility/Utility Engineers, Consulting Engineers, Technicians and Technologists, Municipal Planners, Plant Managers, Plant Operating personnel
