Desal URN test

Seawater Desalination Research Each data point from the above fluxand-recovery matrix was input to a net present value (NPV) model to determine the most affordable point (MAP) of operation. As part of determining the MAP, a specific set of water-quality goals was established based on EPA Secondary Water Treatment Goals (TDS < 200 mg/l and boron < 1.045 mg/l ). In some cases, where these goals were not achieved at any of the matrix operating points, the ADC simply ran the demonstration at the MAP, noting the higher TDS and boron figures. Note that T the test protocol outside the NPV analysis provides general water-quality goals of TDS < 500 mg/l and boron < 1.45 mg/l, to account for applications that may have less stringent water-quality requirements. At the end of the 12-point matrix testing and at the end of the 2-3 week MAP testing, the baseline conditions of 42.5% recovery and 7.5 gfd were retested to confirm that membrane and system performance had remained stable from the first two weeks of testing. • California Department of Water Resources • California Energy Commission • Carollo Engineers • City of Santa Cruz Water Department • Energy Recovery, Inc. • FilmTec Corporation • GE Zenon • Hydranautics – A Nitto Denko Company • Koch Membranes RESULTS AND DISCUSSION Raw Water Quality Raw feed water was taken from an open intake at the end of a pier located in the Port Hueneme shipping channel fed by the Pacific Ocean. Typical seawater quality tested during this study is summarized in Table 3 (see page 32). As noted, the SWRO average feed water temperature was 59°F/15°C with a high of 68°F/20°C and a low of 54°F/12°C. It should be noted that once through cooling applications using a co- ADC Mission and Members he mission of the Affordable Desalination Collaboration (ADC) is to demonstrate affordable, reliable and environmentally responsible reverseosmosis (RO) desalination technologies and to provide a platform by which cutting-edge technologies can be tested and demonstrated on their ability to reduce the overall cost of the seawater reverse-osmosis (SWRO) treatment process.
