I think it depends on what scale you are looking to purify the water.
If you are looking at a small scale, like for your house or some such, I think a solar still is the most economical. It is kind of like a greenhouse that evaporates the water from the waste water, and lets it run down a slanted roof into a trough. What you get is a source of fresh water, and some left-over sludge which you flush out once a day. You can check out the details at http://www.i4at.org/surv/sstill.htm and other websites.
