Modern, cost-effective, sustainable and proven for any scale and treatment objective

Compared to activated sludge technologies, the biological treatment power of Nereda is much larger. It saves up to 50% on energy costs whilst delivering 'high quality' effluent at low costs, and requires only a quarter of the land area of conventional activated sludge installations.

Moreover, the technology unlocks recovery of precious resources like water, phosphate and Kaumera® biopolymers, and can be retrofitted into existing infrastructure to boost treatment capacity or purification level.

Development of the Nereda technology shows how close public-private innovation partnership can result in a whole new era of wastewater treatment, with big advantages for people, planet and societies all around the world.
