A western Pennsylvania company last week opened a plant in Tioga County for treating wastewater from shale gas drilling in northern Pennsylvania.
The plant offers "a tiered menu of services, including filtration, disinfection, solids handling, pretreatment and evaporation concentration," the company, Aquatech International, said in a statement.
The site can process up to 200 gallons per minute, according to press reports. Globally, the Canonsburg-based company said it treats more than 1 million gallons of water a day for the oil and gas industries.
The hydraulic fracturing, or "fracking," process uses several million gallons of water per well. Because of concerns about contamination, Pennsylvania has tightened its regulations on the disposal of fracking wastewater; many drilling companies have shifted to recycling all or most of their flowback water for reuse in future fracking operations.
