Sewage treatment using a granular sludge reactor

A state-of-the-art sewage treatment plant that uses Nereda technology. This innovative technology through which compact granules are formed, is faster, cleaner and cheaper than the conventional method in which flakes are formed.

A university, the business community and water authorities (Delft University of Technology, consulting and engineering firm DHV, the Foundation for Applied Water Research(STOWA) and six water authorities) together developed this sustainable Dutch technology with the aim of reducing the costs of water purification. The Nereda process is based on a group of micro-organisms that form compact sludge granules which quickly sink to the bottom. This enables household wastewater to be purified four times faster than when traditional technologies are used. The results is an energy saving of over 20 percent while the process is also faster and takes up less space.  

Opening sewage treatment plant

On 8 May 2012, in Epe, Crown Prince Willem-Alexander and State Secretary Atsma (Ministry of  Infrastructure & the Environment) officially opened the first sewage treatment plant using the Nereda technology.
