Long Beach Nanofiltration Prototype

Reclamation has been working with Long Beach (CA) Water Department on the development of the two-pass nanofiltration desalination process they invented and had developed to the bench scale. Initial data on this process indicates that it can desalt seawater using substantially less power than conventional reverse osmosis. During 2005, Reclamation assisted in the development of the test plan and provided technical assistance for construction of the 300,000 gallon per day prototype unit.
