None that I know of unless you count camping at the side of a river and using sand to clean the pots, pans and dishes.

If you looked inside a dishwasher's water softener, and saw what you described as "sand", that stuff is in fact tiny granules of a special "ion exchange resin".
When fresh water is passed through it the resin exchanges sodium - from the salt (sodium chloride) which you must use to recharge the water softener - for the calcium, magnesium, and other elements which cause water to be "hard" and leave "scum" behind around sides of baths, in clothes after they have been washed, deposit "scale" inside water-heating kettles and furnaces, etc.
The water which exits from the water softener after treatment thus contains sodium-based compounds which remain dissolved in the water and don't leave behind any hard scum or scale when the water is heated and used with soap or detergent. That is why such water is known as "softened water".
Further Note:
When compounds of such elements are dissolved in water they split up into positive and negative components known to chemists as "ions".
