H2O Innovation has been involved in supplying nanofiltration (NF) and reverse osmosis (RO) systems for municipal and industrial applications since the 1990s through the acquisition of Membrane Systems, Inc. (MSI), a San Diego legacy company. Several employees from the original group that began MSI continue to work for H2O Innovation to this day. MSI began building systems in 1990 and became a major player in for municipal and industrial membrane systems in the US and abroad with hundreds of successful references.
NF/RO applications are used to remove unwanted salts and contaminants from a feed water stream. It is commonly used in drinking water, water reuse and desalination applications. Systems are designed to achieve removal of TDS, TOC, alkalinity, sodium, chloride, phosphate, iron, manganese, arsenic, boron and other salts or contaminants based on membrane projections which simulate the rejection of these contaminants by the NF/RO membrane.
