UTSA, SwRI researchers to develop low-cost method to treat fracking water

Eagle Ford Shale

Share this Story

(Aug. 6, 2013) -- Researchers at The University of Texas at San Antonio (UTSA) and Southwest Research Institute (SwRI) jointly announce they are investing $200,000 in new research to develop a low-cost method to treat flow-back water following hydraulic fracturing. Over the next year, the researchers will optimize an inexpensive charcoal product called biochar for the water treatment solution. It will be tested on water samples from the Eagle Ford Shale.

Flow-back water treatment is currently a critical sustainability issue for the oil and gas industry. By sheer volume, flow-back water is expensive to treat because a single well can require one to five million gallons of fracking fluid. Environmental factors also must be considered because flow-back water includes salts, hydrocarbons and heavy metals, making it unsafe for disposal on land and in streams.

UTSA mechanical engineering faculty member Zhigang Feng and SwRI senior research scientist Maoqi Feng believe that they can alter biochar derived from wood chips to create an economical and environmentally friendly solution. Produced from pyrolysis of biomass, biochar is a stable charcoal-like solid that attracts and retains water, absorbing up impurities such as hydrocarbons, organics, biocides and certain inorganic metal ions.

Over the course of the study, the researchers will isolate, prepare and characterize the biochar; test the biochar on flow-back water samples from the Eagle Ford shale; develop computer models of the biochar water treatment system; and assess the biochar performance for possible improvements.

If successful, they expect the biochar treatment to be the second step of a two-step water purification process. The first step would include filtration to remove the solids in the water remaining from the fracking process. The treated water would then be ready for re-use or safe disposal.

The Connect program, an annual UTSA-SwRI joint funding initiative, was established in 2010 to stimulate inter-organizational research between UTSA scholars and SwRI investigators in fields such as advanced materials, chemistry and chemical engineering, energy, the environment, security and manufacturing.

For acclaimed UTSA writer, poetry rhymes with life

Robert Penn Warren said: “How do poems grow? They grow out of your life.” That is certainly true for Carmen Tafolla. An associate professor of practice with the UTSA College of Education and Human Development, Tafolla has authored more than 20 acclaimed books of poetry and prose, including "The Holy Tortilla and a Pot of Beans." It won the Tom´s Rivera Children’s Book Award in 2009.

Tafolla is a San Antonio native who grew up on the West Side. Attending a private high school, she realized that the literature did not positively portray her community or the people who lived there. She determined to change that in her writing. In published works for both adults and children — more than 200 anthologies, magazines, journals, textbooks and readers in four languages — Tafolla reflects on the rich Mexican-American culture of San Antonio in which she grew up.

Did you know? Tafolla was San Antonio's first Poet Laureate, from 2012 to 2014, and currently serves as the Poet Laureate of Texas.
