According to MIT, this technology works even at small scale, with one the size of a suitcase able to desalinate 6 litres per hour, and only needing to be serviced every few years.

Here's a video detailing how it works.

Because the device is tilted, saltier water flows out of the device and back into the main salt water reservoir due to having more mass than the less salty water. As long as the main reservoir was regularly flushed with new salt water, it would never become dangerously concentrated to marine life, which is a major advantage.
