Landfill is currently the industry standard for disposal of end-of-life reverse osmosis membranes. Due to their mostly polymeric composition, membranes are considered inert municipal solid waste in the case of landfill disposal, with no degradation over a measureable time period. Therefore, disposal in landfill has the highest environmental impact of all the considered options, and should be avoided where possible; however, it is the simplest option, with minimal cost.

This membrane end-of-life (MemEOL) tool is aimed at 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. This dynamic and interactive educational tool uses inputs on membrane condition and the relative importance of a number of key criteria to provide recommendation and further information about available end-of-life options.

As user feedback is obtained, and more available end-of-life options are identified and characterised, this tool will become a powerful source of information for membrane users. Ultimately, this tool will include a membrane reuse database, which will allow users to find and contact groups with surplus membrane supplies, thus promoting and simplifying direct membrane reuse. This tool has a significant focus on the Australian desalination industry, but the primary information is highly applicable to countries around the world. Additionally, as the data sources for this tool are not case specific, it should only be considered an educational tool aimed at providing preliminary recommendations to users.

Do you suspect there is any physical damage to the membranes that would prevent them from being reused?

What is the tested permeability of your membranes (LMH/bar)?

What is the tested NaCl rejection of your membranes? (% NaCl rejection)

Please order the following criteria in the order of importance for your project (drag and drop):

  • Minimal Financial Impact
  • Low Project Complexity
  • Minimal Environmental Impact
  • Minimal Landfill Impact
  • Positive Public Perception
Rank from most important to least important.

Based on your inputs, the optimum end-of-life scenario for your used membrane is:

A suitable alternative is:
