A centralized wastewater treatment facility in Bradford County, Pa., will treat wastewater generated during development of oil and gas wells in the Marcellus and Utica shales.

Construction by Eureka Resources LLC, Williamsport, Pa., will allow for recycling of shale water for use at future well sites. In addition, the plans include a concentrated-brine crystallizer to allow for beneficial reuse of byproducts extracted from the water.

Phase one of the two-phase project includes pretreatment of 10,000 barrels/day of multiple fluids such as drilling muds, flow-back water and produced water. The treated water will be trucked offsite for reuse, temporarily stored onsite for later reuse, or disposed of through an existing facility.

The second phase includes construction of a concentrated brine crystallizer to allow advanced treatment of the pretreated effluent. The unit will generate solid-phase crystallized salt cake, a concentrated liquid brine purge stream and distilled water, depending on the oil and gas operator’s needs.
