The treatment processes include Reverse Osmosis (RO) and Ion-Exchange (IX) for removal of nitrate and total dissolved solids (TDS). The Chino I Desalter also includes air stripping for removal of some volatile organic chemicals (VOC). Approximately 2 million gallons per day of brine, a byproduct of the reverse osmosis and ion exchange processes, which is transported by the Inland Empire Brine Line (IEBL) to Orange County and is subsequently discharged to the ocean. The high-quality water is then pumped into the municipal water supply systems for the cities of Chino, Chino Hills, and into the Jurupa Community Services District water system.
