In late April, more than 80 representatives of government agencies, water utilities, universities, and think tanks gathered in Arlington, VA to discuss the oft-lauded future of wastewater resource recovery.
Microbial capacitive deionization (MCD) shows promise as a sustainable, low-cost treatment solution for produced water.
What happens after you flush the toilet is becoming a big deal. In a just-published article (Reuse Water Pollutants) in the leading science journal Nature, Arizona State University water treatment expert Bruce Rittmann and two colleagues propose a paradigm-shifting change in the treatment of wastewater, a shift they say could have a dramatic global impact.
What’s the most sustainable way of dealing with reverse osmosis and nanofiltration membrane concentrate, particularly in water-scarce Florida? Treat it and drink it.
Chicago is giving its oldest wastewater treatment facility a disinfection facelift and using the world’s largest reservoir to curb combined sewer overflows.

‘Sewer mining’ may sound like a search for mistakenly flushed and washed-away valuables, but it’s actually a sophisticated, sustainable strategy for combating water scarcity.
Each year, the oil and gas industry produces more than 800 billion gallons of wastewater. Coupling the massive volumes of wastewater generated over the life of the well and the millions of gallons of water needed to hydraulically fracture each well, it’s easy to see that oil and gas exploration and production is just as much a water issue as it is an energy issue.
Mines throughout Pennsylvania contain millions of gallons of contaminated water, putting thousands of stream miles at risk.
Wastewater plant managers are well aware that they can put a price tag on the water they treat and the byproducts that result. But many still wonder: what number should that tag show and where will they find the highest bidder?
