Periodically, the resin is recharged by passing a salt water solution through the resin and out the waste water connection. The salt strips the minerals attached to the resin ions where it is released back into the water that is being discharged through the waste connection.
Chemical water softeners added to swimming pools and hot tubs work by sequestering the minerals to the ions contained in the chemical. The minerals are still there, but they are bound to other ions. I sure wouldn't consider that water safe to drink.
You best bet would be an RV portable tank type water softener.
This^^^^^^ We have lived with well water for over 30 years in different homes. In each case we installed a water softener to remove minerals from our water. While I use Calgon water softener to help keep our grey and black tanks clean I wouldn't ever consider consuming it. There's a saying... buy a filter or be a filter.
