Reverse osmosis (RO) and Nano-filtration (NF) are physical separation technologies used to remove contaminants from liquids. Both RO and NF require pressure to function. Both are used in place of conventional treatment technologies. Find out how they differ and how they're similar to make the best choice for your water purification.
