Caption

A superhydrophilic filter produced at Rice University can remove more than 90 percent of contaminants from water used in hydraulic fracturing operations. In this image, 'produced' water from a Marcellus shale fracturing site is at left, the retentate (carbon removed from the feed) is at center, and filtered 'permeate' water is at right. The hydrophilic treatment keeps the filter from fouling and restricting flow while rejecting contaminants.
