Are you a membrane user? would you like to reduce landfill disposal of end-of-life membrane modules? Please, help us by filling out this baseline form
Fulfill the survey will not take longer than 5 min.

Filling this survey you will contribute to

1. A technical-social analysis within the Mem2.0 project.

2. Upgrade the MemEoL online available tool create by a team of researchers at UNSW (Sydney, Australia) . Currently, the main objective of this tool is promoting better practices in the desalination industry by helping users identify and select the optimum end-of-life option for their used reverse osmosis (RO) membranes.

3. Upgrade a Web-mapping created by IMDEA Water researchers (Madrid, Spain). It shows alternatives of end-of-life membrane management to landfill disposal. The main aim is to network public and private entities Globally. If you are part of this community and you did not find your institution at the web-mapping, please contact us!!!

Any question, proposal, discussion.. you can further communicate us at or

Mem2.0 project with reference TECSPR17-1-0019, has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 712949 (TECNIOspring PLUS) and from the Agency for Business Competitiveness of the Government of Catalonia. Research activity is conducted at University of South Wales (UNSW, Australia) and University of Girona (UdG, Spain). This survey has been created in collaboration with Life-Transfomem consortium (
