Water Standard Company has spent six years developing an ocean going ship that houses a self-contained seawater desalination plant. The ship includes a multidepth intake line, microfiltration, reverse osmosis, and posttreatment systems to convert seawater to potable water. They claim this will be more cost-effective than a land-based reverse osmosis plant. It sounds pretty cool.
In October, the Monterey Peninsula Water Management District Board of Directors voted unanimously to add the this ship to its matrix as an alternative water source.
Could this be answer in US coastal areas? Stay tuned. So far, there are no confirmed purchase orders.
