Is there a portable water recycling unit that one could install in their studio apartment to recycle grey water ? Or which is the smallest grey water recycling unit ? And can't someone just pass the grey water thru their reverse-osmosis filter and reuse the water?
You can make your own filter,I think. When I was kid me and me father constructed or own filter, everything you need is some sand, 'dust coal' and a couple of stones and wool. You can use a bottle of soda, or something like that. Put the wool on the 'mouth' of the bottle (I'm not a native english speaker, and I don't know some words, I will put inside a quote), then put the coal, stones and sand. Put a another bottle under the will to extract the clean water. If you want, I can make a draw, to make it more clear to understand.
I know that one is launching soon. I saw it on my friends FB feed. Here's the link to the video. http://www.youtube.com/watch?v=-tELefN4DWQ
