An Introduction to Primary Wastewater Treatment

COURSE NO: C02-034
PDH CREDIT: 2
An Introduction to Primary Wastewater Treatment
Course Highlights

This online engineering PDH course will introduce you to processes and equipment for primary treatment of wastewater. You will be introduced to descriptions, functions and design considerations for sedimentation tanks and clarifiers, chemical precipitation, and Imhoff tanks.  You will learn how the primary treatment processes works together with the preliminary, secondary, tertiary and sludge handling processes to form a complete wastewater treatment plant.

 

Wastewater treatment is usually characterized as consisting of four sequential processes: preliminary, primary, secondary and tertiary treatment. 

 

This 2 PDH online course is intended for civil, environmental and chemical engineers as well as construction professionals seeking an introduction to primary wastewater treatment.
