The problem is that they're kinda wasteful, as, in the typical RO setup, more water will go down the drain in the filtration process than ends up getting filtered.  |
You should have 2-3 filters before the membrane and a carbon filter after the membrane. If you don't have any filters before the membrane, you need to change the membrane much more often. Plus it's a good idea to have something to energize the water right before the faucet.
As for the wastewater... here quite a few people have systems where they use it to flush the toilet.
