Introduction text

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):

  • Financial
  • Effort required
  • Environmental impact
  • Landfill impact
  • 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:
