Welcome to NEREUS Decision Support Tool

The NEREUS Decision Support Tool is a web-based tool designed to aid public and private decision-makers in the decision-making process and speed up implementation of resource recovery from urban wastewater. Nereus DST provides the environmental and budget-friendly treatment trains that can recover water, energy and nutrient.

To start using the tool, please go to User Input from the navigation buttons. It is recommended to look at the User Manual before using the tool.

What is NEREUS about?

Log Cabin The NEREUS project wants to boost the transformation of wastewater into a valuable source of water, nutrients (e.g. cellulose, nutrients), and energy that could be reused in the Interreg 2Seas area. Due to the climate change, there is an increasing water scarcity. For this reason, there is an increasing need to reuse wastewater. Finite nutrients such as phosphorus are crucial for agriculture and currently not recovered from wastewater. As a result, these resources cannot be reused in a meaningful manner (e.g. as fertilizer).

Wastewater also contains energy and heat that could be used as a sustainable source of energy in order to reduce CO2 emissions. Around Europe, the conviction grows that future arrangements for the treatment of wastewater should be based on the principles of a circular economy. Although the technology is available, we still notice that decision makers are hesitant to implement the technology due to the lack of practical evidence.One of the objectives of the Nereus project is to deliver this evidence and to convince both private and public decision makers.
