Issue

Inefficient operation waste water treatment plant

The operations of the WWTP can be more efficient.

Nitrous oxide is a heavy greenhouse gas, it arises during the purification proces in the aeration tanks at wastewater treatment plants.

Solution

Risk model for nitrous oxide

The risk model makes it possible for every wastewater treatment plant to make an estimation about its nitrous oxide emission  on the basis of a few process parameters. It can also make proposals of possible mitigation strategies.

Pros

  • No long-term measurements with expensive equipment required.
  • Applicable on every wastewater treatment plant.

Characteristics

  1. Topic Water chain
  2. Development state 6: System/subsystem model or prototype demonstration in a relevant environment
  3. Water type Waste water
