    Reverse osmosis is capable of removing dissolved salts (ions), particles, colloids, organics, bacteria and pyrogens from the water. A RO membrane rejects contaminants based on their size and charge. Any contaminant that has a molecular weight greater than 180 Da is most likely rejected by a properly running RO system.
