“…Deep-bed filters (e.g., sand, anthracite coal, walnut shell filters) can be used to remove larger suspended solids and coagulated particles from water. In the case of walnut shells, some residual oil may also be removed along with the suspended solids (Hayes and Arthur, 2004;Rahman, 1992;Srinivasan and Viraraghavan, 2008).…”

Greenhouse Gas Control (2016), http://dx. a b s t r a c tIf large-scale CO 2 sequestration operations are implemented in oilfields or coal mines, large volumes of water (i.e., produced water) could potentially be generated that would need to be properly managed. In this work, produced water samples with total dissolved solids (TDS) values of 18,000-102,000 mg/L (ppm) were collected from an oilfield, a coal-bed methane field, and a coal mine in the Illinois Basin of the United States and were treated by selected conventional pretreatment processes followed by a reverse osmosis desalination process. Pretreatment processes included coagulation by lime, ferric chloride, or aluminum sulfate; filtration by sand, walnut shells, anthracite coal, or microfiltration; and adsorption by organoclay, activated carbon, or ion-exchange resins. Selected pretreatment processes were sufficient for removing most of the contaminants, but the high sodium background of the high-TDS produced water (102,000 ppm) limited the effectiveness of the ion-exchange pretreatment in removing scale-forming species. Reverse osmosis was a practical process for desalination of pretreated produced water samples tested (by reducing the TDS more than 96%) except for the high-TDS produced water. Reported benchscale produced water treatment data might be beneficial for the design and operation of pilot-scale plants for treating produced waters with similar properties.

“…Traditionally, activated carbon has been widely used as an adsorbent for removing oil. Various adsorbents such as crushed and/or processed plant materials [2][3][4], horticultural peat [5], bentonite organoclay [6], vermiculite [7], chitosan [8], reed canary grass, flax and hemp fiber [9] and walnut shell media [10] have been examined for their oil adsorption capacities.…”
