Overview
At the U.S. Navy Seawater Desalination Test Facility (SDTF) in Port Hueneme, NanoH
2O achieved a 17% reduction in operating pressure and a 10% reduction in specific energy when compared to conventional membranes under the same operating conditions.
Feedwater enters through a screen-fed open ocean intake into an ultrafiltration (UF) pretreatment system for the seawater reverse osmosis (SWRO) that consists of five 2-element vessels plumbed in series. All elements tests were conducted with only four of the five vessels resulting in a seven-element-in-series, single-pass array. An ERI PX energy recovery device and variable frequency drive-controlled positive displacement Danfoss axial plunger pumps were used to allow efficient operation over a range of operating conditions.
