Biological wastewater treatment

The challenge for many cities and industries around the world is to find cost-effective, sustainable and simple solutions for sanitation that have a small footprint and meet the most stringent purification requirements.

Nereda offers that solution. Nereda is the innovative, sustainable and cost-effective biological wastewater treatment technology that purifies water using the unique features of aerobic granular biomass. Nereda plants require a quarter of the area of traditional installations; the process consumes much less energy; and it is entirely based on natural ingredients. Furthermore Nereda is more effective and less expensive than traditional methods, it is more efficient in terms of land use, resources and energy. This leads to cleaner water, at lower economic and environmental cost.

Research and development

The award-winning technology was invented by the Delft University of Technology in the Netherlands and developed in a unique public-private partnership between the University, the Dutch Foundation for Applied Water Research (STOWA), the Dutch Water Boards and Royal HaskoningDHV. After 20 years of research and development this innovative biological solution is now proving itself to be a leap forward in wastewater treatment technology.

International

Nereda is being used internationally for the sustainable and cost-effective treatment of industrial and domestic wastewater. With tank sizes already similar to the world’s largest SBR-tanks, the technology is proven and suitable for even the largest applications.
