Nereda® is a sustainable purification technology in which the purifying, active sludge does not form flakes, but granules. This makes the sludge settle much faster and easier. The technology has a high purification efficiency, takes up little space (no large settling tanks needed) and consumes relatively little energy.
The Nereda® technology is discovered by TU Delft. This technology was developed in collaboration with, among others, the water authorities and STOWA and is currently being marketed worldwide by Royal HaskoningDHV.
