The Technology Behind Every Drop
How does seawater become drinking water? At WEB Aruba, the process centers on seawater reverse osmosis, or SWRO.
High-pressure pumps push water through specially designed membranes that allow water molecules to pass while retaining most dissolved salts. Further treatment, including remineralization and ultraviolet disinfection, prepares the water for distribution.
SWRO uses less energy than the thermal desalination systems (Multistage Flash-MSF) previously used at WEB, helping us produce drinking water more efficiently while maintaining the quality our customers expect."
