  1. Use of modified dolomite for constructed wetlands and filter beds for phosphorous removal • Dr Gavin Walker* and Professor Stephen Allen School of Chemistry and Chemical Engineering, QUB • Project Champion: Viltra • Objectives: this project addresses an important environmental concern, i.e, the removal of phosphate from water sources. • Aim: the project aims to develop and enhance the potential for use of constructed wetlands to remove phosphates from water School of Chemistry and Chemical Engineering QUB

  2. Novelty and Innovation Choice of support medium Granular adsorbents Ability to adapt to loadings Ability to handle different pollutants Simplicity Sustainability Low cost Potential Advantages Dolomite can remove phosphate in the presence of other species Reeds can consume the phosphate from the dolomite No waste product No hazardous chemicals or media regeneration is required Aesthetics Lower O & M costs Sustainable Novelty and Potential Advantages School of Chemistry and Chemical Engineering QUB

  3. Potential EU collaboration with Ecole de Mines, Nantes, France Currently coordinators of EU F7 grant on constructed wetlands Access to full scale wetland systems QUB collaboration via ME3 Erasmus Mundus Programme- European joint Masters of Science in Management and Engineering of Environment and Energy (2007-2013) Consortium: EMN (France); KTH (Sweden); UPM (Spain); BME (Hungary); QUB (UK) Joint PhD students Potential EU Collaboration School of Chemistry and Chemical Engineering QUB
