Here is the NYT article from August 10, 2008 that discusses water-recycling plants. An interesting lunch-time read.
We have hundreds of books on the topic, not to mention ebooks or electronic databases… Check out the following two links:
1. Water–Purification (almost 200 books)
2. Sewage–Purification. (almost 200 books)
Moreover, we have a couple of online books about the topic, for instance – “Handbook of water and wastewater treatment technologies” from Knovel. Check those out!
