The basis for this technology, which is currently rapidly evolving as the new standard for biological treatment of municipal and industrial wastewater, was laid by the research group of prof. Mark van Loosdrecht. Ghent University, Delft University of Technology and Royal HaskoningDHV signed a memorandum of understanding as part of the state visit of the King and Queen of Belgium to the Netherlands. 

Aerobic granular sludge technology is a new way of wastewater treatment in which the bacteria grow in granules. The technology is much more economical and durable than conventional systems: Nereda results in energy savings up to 50%, and requires significantly less investment while a Nereda plant occupies only 25% of the space.

The collaboration with Ghent University means that the technology will be further optimized. Mathematical models should ensure that the systems become smarter and more efficiently to save even more energy, cost and space. The research group of prof. Eveline Volcke at Ghent University is focused on efficient and sustainable process design and process control, and has a distinctive expertise and years of experience in the optimization of water treatment processes based on mathematical models.

Currently there are no Nereda installations in Belgium. This cooperation can be seen as a first step to transfer the technology to Belgium.
