Reverse osmosis, a common method used in some modern water purification systems, works by forcing water through what type of specialized barrier?

Explanation

Reverse osmosis is a water purification method that works by applying pressure to force water through a specialized semi-permeable membrane, one containing extremely small pores that allow water molecules to pass through while blocking many larger dissolved salts, minerals, and other contaminants. This process effectively reverses the natural direction of typical osmosis, which would otherwise cause water to flow toward, rather than away from, a solution containing a higher concentration of dissolved substances. Reverse osmosis systems are commonly used both in certain household water filtration setups and in large-scale industrial and municipal water treatment facilities, including some seawater desalination plants.
