Microfiltration/Ultrafiltration MF/UF systems are used to remove suspended solids (TSS) and high molecular solutes, while water and low molecular weight solutes pass through. Membranes are defined by the molecular weight cut-off (MWCO). Nanofiltration NF is very similar to that of RO, with the major difference is that the NF membrane is not as tight as the RO membrane. It operates at a lower pressure and it does not remove monovalent ions from the water as the RO membrane. NF is suited remove di- and trivalent ions from water while leaving the TDS content less affected than an RO. NF is used to filter low TDS wates, to remove organic matter and soften water. Reverse osmosis RO systems produce water that is relatively pure and free from suspended solids, dissolved minerals, viruses and bacteria. RO has become one of the most cost-efficient technologies for deionizing water. As it relies on few moving parts, RO systems require minimal maintenance when water is properly treated upstream.
