Nanofiltration: key role in the NEREUS resource recovery process

Theme
Energy & Nutrient Factory, Innovation / new techniques

Summary
The goal of this project is to recover mainly phosphate and ammonium with a nanofiltration membrane. At the moment a (combination of) nanofiltration membrane(s) is selected to separate the phosphate and ammonium in such a way that these nutrients end up either in the permeate or in the concentrate. Operational strategies will be tested to increase the net flux of the membranes while maintaining the robustness of the process. Membrane fouling will undoubtedly be a problem and therefore quantification of fouling can also be part of the project. In addition, energy consumption is monitored and determining the CO2 footprint of the system is also an important component.

Results

After a proper selection of the membranes and optimisation of the operational strategies, the nanofiltration membranes will separate the phosphate and ammonium and the pilot system will run smoothly. We will know the energy consumption per m3 of treated water and the CO2 footprint of the system.
