11. Aerobic Granular Sludge

Aerobic granular sludge is an emerging technology with higher sludge concentration and higher efficiency compared with conventional activated sludge systems. This state-of-the-art course covers important considerations for selecting aerobic granular sludge, kinetics of aerobic granular sludge, process control, design considerations, and resource recovery aspects. Case studies, including the Nereda® technology are also part of the course materials, as well as examples and exercises to expand and check your knowledge on the subject. After completion of this course you will understand the basic principles of aerobic granulation and technology, and its applicability to modern wastewater treatment practice.

Course information

  • Learning Objectives

    After completion of this course, you should be able to:

    • understand important considerations for selecting aerobic granular sludge
    • get familiar with the kinetics of aerobic granular sludge, process control, design considerations, and resource recovery aspects
    • grasp the basic principles of aerobic granulation and technology, such as  Nereda®, and its applicability to modern wastewater treatment practice.
  • Syllabus

    This course covers the following topics:

    • Introduction to AGS
    • From Lab- to Full-scale Implementation
    • Process Operation and Control
    • Advanced Process Control
    • AGS Plant Configuration and Design
    • AGS Melody and Nereda case studies
  • Organization

    Courses in this series consist of video lectures, presentation slides, reading materials, exercises, and assignments with solutions. In principle, each video presentation has its complementary presentation slides. All videos are available for viewing in the section “Video-recorded presentations”. The materials are packaged in three (.zip) files, namely, the “Videos”, the “Presentations”, and the “Documents”. Files may be of considerable size, so you need to ensure that your computer has sufficient bandwidth and capacity for downloading. This course is based on the two chapters in the book “Biological Wastewater Treatment: Principles, Modeling, and Design” 2nd edition (Chen et al., 2020). To check and expand your knowledge on the subject, it is recommended to study the corresponding chapter in the complementary book  “Biological Wastewater Treatment: Examples and Exercises” (Lopez-Vazquez et al., 2023). The two chapters are open-access and available in the section “Documents (.zip) on this webpage.

  • Delivery Method

    This course is currently designed for a SELF-STUDY mode. It is FREE, and does not include guidance, support, exams, assessment, and certification.  We also recommend to check the “Aerobic Granular Sludge Technology for Wastewater Treatment” course delivered by our partner Delft University of Technology which includes guidance, assessments, and certificate, using this link.

11.6 Water Melody® Nereda® WWTP Jardim Novo

Did you realize that each time you flush a toilet, shower, or wash your hands, you may contribute to a melody created from wastewater data? This experiment was made possible thanks to the interdisciplinary contribution of a small group of enthusiasts. The idea of making music from sewage data emerged a couple of years ago from Prof. Mijatovic and Prof. Brdjanovic, supported by Prof. van Loosdrecht, and soon after it was picked up by a group of enthusiastic musicians, IT specialists, environmentalists, and technology innovators. The result is here. So, what is the Water Melody®? It is a known fact that modern sewage works are a source of a wealth of data. We have selected the most interesting data, like sewage flowrate and ammonia, nitrate, phosphate, and dissolved oxygen concentrations, and assigned a separate group of musical instruments to each parameter. The HaskoningDHV’s Nereda® plant Jardim Novo in Brazil was selected as a data donor and a couple of Nereda cycles were translated to notes and notes to a melody – this time in salsa rhythm. In this way, the Jardim Novo plant got its unique melody. We have prepared two videos: one with the melody itself and one which shows the making of it.
