WebApr 10, 2024 · Reverse osmosis (RO) water purification is an effective method of greatly reducing nitrates in drinking water. An RO system filters nitrates, and up to 99.99% of total dissolved solids, in a process called membrane separation. Good alternatives to RO filters for reducing nitrate levels are ion exchange systems and water distillers. WebJul 3, 2024 · Updated on July 03, 2024. Reverse osmosis or RO is a filtration method that is used to remove ions and molecules from a solution by applying pressure to the solution on one side of a semipermeable or selective membrane. Large molecules (solute) can't cross the membrane, so they remain on one side. Water (solvent) can cross the membrane.
