The Nametech project harnesses benefits of nanotechnology to bring about improvements in membrane filtration for advanced water treatment. The general objective is to strengthen the European membrane market by making nanotechnology available to large scale European membrane manufacturers. A unique feature of the project is the knowledge transfer between the experienced membrane manufacturer Norit and the coating expert and new-comer to the membrane field Agfa Gevaert.

The S&T focus is on the use of nano-structured materials to alter the physical and chemical properties of polymeric ultrafiltration membranes and thereby improving the filtration performance at macroscale installations. The project aims at adapting commercial nanoparticles such as TiO2 and Ag for the modification of UF membranes to reduce fouling, and thus improve its permeability (i.e. Technology Path 1). In Technology Path 2 and 3, the potential of using active nanoparticles, such as bionano-catalysts, in combination with membranes is examined to remove micropollutants such as chlorinated compounds, nitroaromatic compounds or redox active metals, thus improving the water quality. A specific novelty is the development of an integrated permeate channel concept, whereby the nanoparticles are embedded in 3D textiles, functioning as membrane support and permeate channel.

The nanoparticles will be deposited on the membrane surface or embedded in the membrane (mixed matrix). The S&T challenges regarding the modification of the nanoparticles, the deposition of the nanoparticles on membrane surface as well as the production of nano-activated membranes (NAMs) will be addressed in WP 1, 2 and 3. The newly developed NAMs will be tested at laboratory scale (WP 4) before selecting the most promising concept for testing at pilot scale (WP 5). The activities will be complemented by a toxicological study and the application of LCA to assess the environmental impacts (WP 6).

PROJECT GOALS:

The projects brings together all required elements to enable the transfer of nanotechnology towards the field of water treatment, not just to laboratory scale testing but really reaching the commercialization stage. The broad engineering and application know-how of the partners will be brought together to realize cost reduction and process intensification strategies. The scientific and technological focus is on the use of nano-structured materials to alter the physical and chemical properties of polymeric ultrafiltration membranes and thereby improving the filtration performance at macro-scale installations.
The Nametech project harnesses benefits of nanotechnology to bring about improvements in membrane filtration for advanced water treatment. The general objective is to strengthen the European membrane market by making nanotechnology available to large scale European membrane manufactures.
To limit the scope of this project and to optimize the use of project resources, the focus of the research activities in the field of nanotechnology will be in the application of developed nano-activated materials. As such, the nano-structure materials used in this project will either be the commercially available nanoparticles, or the bio-nano catalysts that are currently investigated by some of the consortium partner. The research objectives will then be to adapt and alter physical and chemical properties of the nanomaterials e.g. particle size, surface chemistry so that the nanoparticles can successfully be deposited or incorporated in or on membranes, preparing i.e. nano-activated membranes (NAMs). The second objective of this project is to evaluate the NAMs in the field of research and technological development in water treatment, i.e. separation, purification and/or detoxification. Research activities will be performed at all levels, ranging from membrane testing with laboratory scale equipments to conducting pilot tests with a single NAM-module under real filtration conditions on-site at the end-user. Operating issues such as the mechanical and chemical stability of the newly developed NAMs as well as the economical issues such as the production cost of the NAMs in comparison to conventional membranes will be dealt with.
