DeNTreat Project
DeNTreat Project: Decentralized innovative treatment of ammonium-rich urban wastewater

LIFE DeNTreat aims at demonstrating an on-site wastewater treatment module meant to sustainably abate nitrogen pollutants from selected (nitrogen-rich) points of discharge in order to reduce nitrogen content of overall urban wastewater.


Starting from a TRL 6 pilot, the project is expected to demonstrate the effectiveness of the proposed solution in a relevant operation environment, testifying an actual saving of up to 40% in investment and operational costs compared to conventional N-removal processes, and an 80% reduction of the N2O emissions during biological wastewater treatment compared to the current technologies.


Complementing traditional wastewater treatment plants (WWTP), the demonstrated module,


Will allow to:

  • obtain a residual N content below 100 mg/l in the wastewater released in the collection system;
  • easily accomplish Directive 91/271/EEC art.5 requirements asking to ensure that the minimum percentage of reduction of the overall load entering all urban WWTP in a given area is at least 75% for total nitrogen produced;
  • assure the respect of residual nitrogen concentration in WWTP discharges, to be maintained below 10 mg/l;

Will enable:

  • an actual saving of up to 40% in investment and operational costs;
  • a reduction of the N2O emissions during biological wastewater treatment to less than 20% of the currently adopted technologies;
  • an abatement of the sludge produced as a result of the nitrogen abatement process to less than 25% of the currently adopted technologies.
