Activated Sludge Wastewater Treatment

The Activated Sludge Wastewater Treatment online PDH course is a part of the Civil Engineering category of courses. This course discusses the activated sludge process employed extensively throughout the world in its conventional form and modified forms, all of which are capable of meeting secondary treatment effluent limits at wastewater treatment plants. This discussion presents the different modifications of the conventional activated sludge process, including general bases for design, methods of aeration, and design factors for aeration tanks, final sedimentation units and sludge handling systems. All designed processes include preliminary treatment consisting of bar screen as a minimum and, as needed, comminutor, grit chamber, and oil and grease removal units.

This course will give environmental and civil engineers and other design and construction professionals an introduction to the design, construction and process control considerations for activated sludge wastewater treatment plants.

This course is intended for civil, environmental and sanitary engineers and other design and construction professionals wanting an introduction to wastewater treatment using the activated sludge process.
