Rejection Ratio of Various Solutes passing through Membrane

The DOW Membrane recently estimated the various solutes rejection ratio in their own production of membrane of FT30 Model

I think, probably most of the membrane’s rejection ratio has to be similar one and note that, solutes Molecular weight also they given, further they indicated clearly this is quick screen, particularly with changes in feed water concentration, pH and temperature [....]


Electrodialysis:The ions in a water solution can be made to migrate by applying an electric field to the solution. By arranging various barriers to the flow of ions, it is possible to directly desalinate water with electricity. Such barriers are called ion-exchange membranes.

Membranes that allow a reasonable flow of cations, but block or reduce the flow of anions, [....]
