Aerobic Granular Sludge Technology for Wastewater Treatment

The introduction of the aerobic granular sludge (AGS) process represents a significant and evolutionary step in wastewater treatment technology.

AGS deploys the treatment characteristics of granular biomass in highly automated sequencing batch reactors. This results in reductions in land footprint, costs, electricity, sludge production, chemical consumption and delivers improved environmental compliance and robustness compared with established wastewater treatment technologies.

In this course you will learn all about the history of and latest developments in the AGS technology, also known as Nereda technology. You will understand its underlying processes and learn how to implement AGS.

You will visit different AGS treatment plants through online excursions and share the experiences of operators, policy makers and innovators from water authorities using this technology. The course offers a basic design sheet for an AGS treatment plant. Additionally, on our discussion forum, after comparing your preferred options –whether you want to be more cost-effective, improve energy efficiency or make environmental improvements to your wastewater treatment plant– you will be able to share your questions and your fellow participants and the course team will help you in your choices!

Prerequisites:

You should have prior knowledge of basic wastewater treatment processes, like BOD, nitrogen and phosphorus removal and activated sludge plants. If you don't have this knowledge, we recommend that you take our Urban Sewage Treatment course. High school mathematics, biology and chemistry are required.

• Explain the basics of aerobic granular sludge (AGS) technology.
• Describe the differences between activated sludge and AGS and explain the microbial conversions in AGS.
• Calculate conversion rates of aerobic granular sludge processes and the dimensions of aerobic granular sludge reactors.
• Explain and design process control strategies for AGS processes.
• Decide on the advantages and disadvantages of the technology in your own situation.
• Create a simple design of an AGS wastewater treatment plant.
