About the event

Why is this conference being held?

The conference is being held to assess the current status of all aspects of the activated sludge process and to look forward to its further development in the future. It is being held at about 100 years from the time that the early developers of the process presented the seminal works that lead to its eventual worldwide adoption.

What are the aims of the conference?

The conference is organized with the aim of assembling the current world leaders in activated sludge research, development, technology and application. The conference objective is to summarize our knowledge of all aspects of activated sludge process and to present and discuss the anticipated future developments.

Who is organizing the conference?

The conference is being organized by the International Water Association and its Specialist Groups on:

  • Design, Operation and Cost of Large Wastewater Treatment Plants, LWWTP
  • Nutrient Removal and Recovery, NRR, and
  • Microbial Ecology and Water Engineering, MEWE

The conference is also being supported by the IWA Specialist Groups on:

  • Sludge Management, and
  • Membrane Technology

The conference is being held in a close collaboration with The German Association for Water, Wastewater and Waste (DWA) and with Ruhrverband and Emschergenossenschaft & Lippeverband, two water companies based in Essen, Germany, the conference venue.

Why Essen?

Essen, a town in the Ruhr area, is a historical centre of German industrialization and in the 19th and 20th centuries it was famous for its coal mining and steel industries. Today Essen is an internationally-acclaimed example of how old industrial sites can be revitalized into to pleasant green towns. The Zollverein mining complex where the conference will be held has been transformed into an impressive complex of museums and conference facilities. The Zollverein mine itself is a listed UNESCO World Heritage Fund Site.

The first full-scale activated sludge plant on the European Continent was built in 1924-1926 in Rellinghausen, which is nowadays part of Essen.

What is the Conference format?

The conference programme will consist of a single platform session with presentations of invited papers by authors. A book containing these papers will form the conference proceedings and will be distributed to all conference registrants. One of the authors of each invited paper will present the paper at the conference. There will be ample time for discussion following the presentations.

There will be a parallel poster session. The poster session will be prepared in cooperation with German Young Water Professionals Organization.

A small exhibition of current and historic activated sludge technology (objects, documents and photographs) will be held. Please contact the conference secretariat if you would like to present such an exhibit.

Time will be set aside for both cultural activities and technical tours.

Who is the conference for?

The conference will be of interest to a wide range of disciplines associated with all aspects of the activated sludge process. The conference programme will be attractive to researchers, engineers, designers, operations specialists, and governmental agencies at all levels. The conference organizers and the German YWP chapter extend a special welcome to young professionals interested in wastewater treatment since it is they who will write the next pages in activated sludge history.
