Methodology

During CeraWater project nanostructured ceramic membranes in honeycomb geometry with outstanding separation properties are being developed. Based on the requirements of industrial processes a high specific membrane area, high permeability, high selectivity and low fouling tendency are aspired. The industrial relevance will be emphasized by the possibility of up-scaling by the modular assembly of honeycombs.

The development will be carried out in close cooperation with membrane producers (Rauschert), end users (VMW, CYCLUS) and further experts in the field of membrane application (Lappeenranta University of Technology, University of Cádiz, IWW) and membrane development (VITO, Fraunhofer IKTS).

Only techniques successfully passing through evaluation as regards their performance compared to existing membranes (including LCA, BCA) will be processed further for up-scaling and pilot implementation.

An iterative development, a close cooperation of all partners of a broad scientific know-how and extended technical experiences and the development of a milestone concept from the beginning of the project minimizes the risk of failing the project aims.  

By the subsequent preparation and coating of the honeycomb like multichannel tube HCNF1 (with more than 160 channels) and honeycomb HCNF2 we are strongly elevating the chance to get a membrane with convincing separation properties and to develop an adapted and optimized separation process.

As CeraWater is a complex and multi-faceted project, the activities of the project are arranged within 10 work packages that are schematically shown and described below. 

WP2 to WP4 deal with the development of materials, with a focus on ceramic honeycombs (WP2), NF coatings (WP3) and specific Anti-Fouling Coatings (WP4).  The latter WP is already at the interface of the “Testing” area of CeraWater which also comprises WP5 (Membrane Characterisation). WP6 focuses on the development of module design and the treatment process. Within application tests and process fine tuning (WP8) the modules and membranes will show their potential for water treatment. This step is followed by pilot testing and prototype application in WP9. These investigations will allow a techno-economical and ecological benchmarking of the new HCNF membranes and membrane process (WP7). In order to maximize the impact and implementation of project findings, there is a specific work package dedicated to dissemination and exploitation activities (WP10).
