Nereda® Aerobic Granular Sludge Technology
Invented by Professor Mark van Loosdrecht at the Technical University of Delft in the Netherlands, Nereda aerobic granular sludge has changed the way the world treats wastewater biologically. Proven at full scale since 2005, Nereda is now enabling wastewater treatment plants on six continents to increase capacity, enhance nutrient removal, and reduce operational costs – while also reducing energy and chemical use. It’s popular as both a new build and retrofit solution.
Compared to conventional activated sludge, Nereda typically achieves better performance with:
Benefits
Small footprint
Lowest lifecycle cost
High effluent quality
Flexible installation
Simple operation
Future-proof
Easily scalable; Key to delivering Net Zero and achieving energy neutral/positive WwTW’s
Nereda wastewater treatment technology - how it works
How Nereda works
Nereda microorganisms grow naturally in compact granules containing aerobic, anoxic and anaerobic biological zones. A repeating three-step cycle of fill and draw, aeration and rapid settling enables several treatment processes to occur in one reactor.
