Siemens to treat wastewater from hydrofracking

Siemens Water Technologies is providing Hydro Recovery LP with a wastewater treatment system to treat natural gas hydraulic fracturing wastewater (flowback) from Marcellus Shale drilling as well as produced water from operating wells in Tioga and surrounding counties in northeastern Pennsylvania.

This flowback and produced water waste treatment system will be part of a new wastewater treatment plant in Tioga County and include continuous precipitation and sludge dewatering. By using the Siemens system, the wastewaters will be treated to produce a Hydraulic Stimulation Fluid (HSF) product for reuse, reducing the demand on fresh water sources. The plant is scheduled to go online in April 2011.

Shale gas is natural gas produced from shale rock fields. This gas has become an increasingly important source of natural gas in the United States over the past decade, with interest also spreading to potential gas shales in Canada, Europe, Asia and Australia. Gas production in commercial quantities in these fields requires fractures to provide well permeability, and modern technology in hydraulic fracturing allows the creation of extensive artificial fractures around well bores. Hydraulic fracturing, however, results in the production of wastewater that must be treated.
