Efficiently, you're making water go in the opposite direction to which osmosis would usually make it take a trip (not from a less-concentrated option to a more-concentrated remedy, as in osmosis, yet from a more-concentrated remedy to a less-concentrated remedy).

Like turned on charcoal, reverse osmosis is excellent at eliminating some contaminants (salt, nitrates, or limescale), but less reliable at eliminating others (bacteria, for example).

The salt is merely a my site various kind of impurity, so you can not define the end item of ion-exchange purification as "pure water" (the included salt can also be bothersome for individuals on low-sodium diet regimens).
