Reverse osmosis (RO) is indeed a method of water purification that removes contaminants from water by using pressure to force it through a semipermeable membrane. This membrane allows water molecules to pass through while blocking larger molecules, impurities, and contaminants, effectively producing cleaner drinking water. It's a popular method used in both residential and industrial settings due to its efficiency in removing various substances, including minerals, salts, bacteria, and other impurities.

process that uses a partially permeable membrane to remove ions, molecules, and larger particles from drinking water. The reverse osmosis process is a type of filtration that relies on pressure to force water through the membrane, which allows water molecules to pass while blocking contaminants.
