What is the main purpose of reverse osmosis in water purification?

• A. To add minerals back into the water
• B. To remove dissolved salts and impurities
• C. To enhance the flavor of the water
• D. To increase the water temperature

Answer: (B)

The main purpose of reverse osmosis in water purification is to remove dissolved salts and impurities. This process involves pushing water through a semipermeable membrane that allows water molecules to pass while blocking a wide range of contaminants, including salts, heavy metals, and other dissolved solids. By effectively separating these impurities from the water, reverse osmosis helps produce clean, purified water suitable for drinking and other uses. This purification method is particularly valuable when dealing with brackish or seawater, where salt content can be high. The ability to eliminate harmful substances not only ensures the safety of the drinking water but also improves its overall quality.
