How to Separate Salt and Water

+

Dec 03, 2019 · Other Methods to Separate Salt and Water . Another way to separate salt from water is to use reverse osmosis. In this process, water is forced through a permeable filter, causing the concentration of salt to increase as the water is pushed out. While this method is effective, reverse osmosis pumps are relatively expensive.
