New wastewater treatment process is piloted at WWTP Scheemda
After the summer, Waterboard Hunze en Aa’s will start with testing a new wastewater treatment process at the municipal wastewater treatment plant of Scheemda, in the northeast of the Netherlands.
In the process nitrogen and phosphate are removed from the wastewater and concentrated into a reusable product. The new technology furthermore saves costs and energy. The pilot test will last 6 months and is carried out by a consortium consisting of Waterboard Hunze en Aa’s, Stowa, LeAF, HITC, NedMag, waterschap Noorderzijlvest en de Technical University Delft.
The new wastewater treatment process removes nitrogen as gaseous ammonia. Ammonia then is used as fuel in a modified fuel cell for generation of electricity and heat. In this way sustainable ‘yellow’ energy is generated from urine and municipal wastewater.
The technology also recovers phosphate as a high-value commodity for the production of amongst others food and fertilizer.
The project is financially supported by Agentschap NL from the Innovation Program Water Framework Directive from the Dutch Ministry of Infrastructure and the Environment.
