I think this has to do with the fact that water soluble wastes are harder to remove from water but easier to concentrate. I'm no chemistry expert but I think that's why

But, given that's the case, what do they do with the wastes? Is it shot out into space or brought back to earth?

Most trash is burnt in atmosphere when the one-way supply ships are disposed (de-orbited in a controlled way). Some waste samples are probably brought down for examination.
