Do you have a solvent filtration process?
You do solvent filtration if your process stream contains more than 10 wt% solvent. Above this level, the solvent may attack your membrane material. This can lead to a change in retention or even to a total dissolution of your membrane. Depending on your solvent and your process conditions this can happen sooner or later. Selecting the right membrane therefore becomes crucial even to laboratory separation process that handle solvents.
