Affordable desalination deemed success
The Affordable Desalination Demonstration Project was launched two years ago, and set out to demonstrate that seawater reverse osmosis (SWRO) desalination could produce a cubic metre of product water for an energy cost of 1.7kWh. It also sought to establish the relationships between RO reject rate, membrane salt rejection, permeate quality, boron levels, feed pressure and energy consumption. Thomas F Seacord of Carollo Engineers, Steven D Coker of FilmTec Corporation and John MacHarg of the Affordable Desalination Collaboration demonstrated a very successful outcome in a paper presented to the American Membrane Technology Association Conference in August. The following article is adapted from the paper presented at Anaheim.
