In addition, membrane desalination technology has the capacity <br />to remove organic carbon, viruses, cryptosporidium and other contaminants which are of <br />health concern. There is an increasing number of full-scale projects, which successfully <br />demonstrate the technical capabilities of brackish water desalination. Desalination is a proven <br />technology that has long been applied in the production of high-purity industrial water and <br />domestic bottled water. <br /> <br />When desalination treatment is necessary, the main technological options available include: <br /> <br />o Reverse Osmosis (RO) <br />o Nanofiltration <br />o Electrodialysis Reversal (EDR) <br /> <br />BOOKMAN-EDMONSTON Section 2 <br />ENGINEERING, INC. 2-24 Salinity Problems, Impacts, & Technology <br />O:\LOCALRES\ANDYS\SALINITY\JUNE98-3\6SECT2.DOC Last printed 08/18/98 9:45 AM <br /> <br />e <br /> <br /> <br /> <br /> <br /> <br /> <br />. <br /> <br />. <br />
