As demand for new energy sources grows, the wastewater co-produced alongside oil and gas (produced water) shows no signs of slowing down: The current volume of wastewater—the result of water forced underground to fracture rock and release the deposits—is estimated at 250 million barrels per day, compared to 80 million barrels per day of oil. The surfactants will cause wetting of the membrane, which will deteriorate the quality of the recovered water.
