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.

There isn't much that gets through in reverse osmosis. It's very soft water.

Lithium extraction is exciting, though. There's some projects out there that suggest the process would be profitable on the non-lithium minerals alone, and then you get clean drinking water on top of it.
