Influences of inorganic salts on the pervaporation properties of zeolite NaA membranes on macroporous supports

- Effects of salts on PV dehydration performance of zeolite membranes were studied.
- Effects of five salt species on the membrane performance were studied.
- Different salts had different impact on the membrane flux.
- Membrane regeneration was performed.
- An irreversible flux drop was obtained.
