Removing Oil from Water
Simple, Inexpensive Tech from Purdue University
This is new innovation that is noteworthy. Purdue University scientists have developed a simple and inexpensive method to remove oil from water. Why does that matter? The potential of this new technology is to cut pollution and health risks globally.

The process was developed for "produced water" from oil refining. 2.5 billion gallons of produced water are generated daily by oil refineries. According to the US Environmental Protection Agency, the produced water has been an intractable contamination problem and hazard. Purdue researchers say they have developed a purification system that is a breakthrough.
Solar Power+Charcoal+Foam & Goes Full Circle
The Purdue process relies on solar-powered charcoal foam. The charcoal is heated up by solar energy to absorb petroleum. The scientists have demonstrated that their process filters out almost all of the oil, making it safe to drink. And, this process goes full circle. Almost 95% of the oil captured in the charcoal foam can be pulled out and reused.
