N.E.W.B.I.E.S. Pilot Installation

Current status: experiments running on reject water

Last updated: 29 december 2019

On this page, you’ll find more information on the pilot installation that has been developed as part of the N.E.W.B.I.E.S. project.

Along with the most notable (physical) characteristics of the installation, up-to-date Key Performance Indicators (KPIs) of the installation as they result from operation on different waste waters will be presented.

Design principles

  • Removal and recovery of 1 kg N / day from selected waste waters
  • At a electrical energy expense of less than 2.75kWh per kg N recovered
  • automated cleaning-in-place procedures to minimize waste pre-treatment requirements
  • future upgradeability – omit use of external stripping acid
