Your rely is not helpful. The problem with any desalination system is that it creates brine. And brine in large amounts is toxic to the marine environment.

The only difference with this example is its small scale. Once it is scaled up it will have the same problem as any existing desalinating plant.

But you would never scale this system up - it's entirely inefficient compared to reverse osmosis, on a cost basis. This is the type of system that you would use for just a few people, and as such - brine would never be an issue.
