A partial waste polymeric material substitute actually improves the process though increased energy retainment and promotion of the foamy slag, which help protects the electrodes and walls of the furnace. There are however strict requirements for feed quality for this process and any type of contamination can lead to a negative impact on steel quality. Therefore, after the membrane components have been grown to the required size, the material needs to be thoroughly washed to remove any contamination from membrane use. This end-of-life option is most suitable for membrane users with a large number of membranes, or when constant replacement is required. | A partial waste polymeric material substitute actually improves the process though increased energy retainment and promotion of the foamy slag, which help protects the electrodes and walls of the furnace.

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.
