Name a common method for removing dissolved solids from water.

Reverse osmosis is a widely recognized and effective method for removing dissolved solids from water. This process involves pushing water through a semi-permeable membrane that allows water molecules to pass but blocks a majority of dissolved solids, including salts, sugars, and contaminants.

The pressure applied in reverse osmosis forces the water to move from an area of higher concentration of dissolved solids to an area of lower concentration, effectively separating the clean water from the dissolved substances. This method is particularly advantageous for applications requiring high purity, such as drinking water, food processing, and pharmaceuticals.

In contrast, while filtration can remove larger particles and some contaminants, it does not effectively remove smaller dissolved solids. Boiling is useful for disinfecting water and can precipitate some minerals, but it does not remove dissolved solids comprehensively. Evaporation can concentrate dissolved solids rather than remove them, as the solids remain after the water has turned to vapor. Thus, reverse osmosis stands out among the other methods for its efficacy in effectively reducing the concentration of dissolved solids in water.
