As long as the salt is returned in a fashion that avoids too high a salt concentration in any single area, and the process does not turn the salt into something noxious, then returning the salt to the sea seems less harmful then trying to store it long term on land.<br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7018073541417646773.post-11901392636164549852015-05-10T09:55:45.895-04:002015-05-10T09:55:45.895-04:00I read many years ago that the salts left over fro...I read many years ago that the salts left over from desalination processes can be combined with other minerals to produce bricks, blocks, and similar building and paving materials.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7018073541417646773.post-51429589767347687592015-05-09T11:18:16.618-04:002015-05-09T11:18:16.618-04:00In addition to getting rid of salt (which makes wa...<i>In addition to getting rid of salt (which makes water unusable for crops and for drinking)</i><br /><br />I don't think extracting salt from water "gets rid of" it. In fact, I always wonder what we'd do with all the salt if desalinisation became commonplace. I believe there's a certain lake out in the western US that underwent a natural desalinisation by evaporation, and now goes by the name of Great Salt Lake, a tourist attraction that will forever be "unusable for crops". How much of that can we do artificially before we poison too much of the land?Anonymousnoreply@blogger.com
