Filtration is the only way to separate salt and sand from water.

Salt can get dissolved in water, but sand will settle down after some time. Then we can filter the sand through the filter paper. Till here only sand is separated. Now, the remaining filtrate has dissolved salt in it. To separate the salt from the water, we can boil off the water. After some time, the water gets evaporated, leaving behind the salt. Hence, filtration and evaporation are both needed to separate salt and salt. Thus, the given statement is FALSE.
