Transportable Frac-Back Water Treatment Unit

United States


In order to provide a cost-effective solution for wastewater treatment and reuse in the oil and gas industry, PACE has conducted extensive research and development in our in-house laboratory facilities, as well as several on-site piloting and demonstration studies. PACE staff have visited numerous oil and gas exploration sites in North America, including California, North Dakota, Utah, Colorado, Texas, Pennsylvania, Ohio, and Alberta, on multiple occasions and analyzed and tested more than 20 shipments of flowback and produced water from hydraulic fracturing operations for oil and gas, as well as conventional oil and tar (oil) sands production. As a result, PACE developed the PEARL BLUE containerized mobile water treatment system. This system can be quickly deployed to any oil and gas production site.


Many of the processes are automated with online sensors and meters, as well as an integrated control system that can be monitored and controlled remotely. Thus, the treatment system can be managed by one trained operator. The PEARL BLUE system also functions as an on-site laboratory facility to analyze water quality immediately. Once operations are completed, the system can be demobilized, cleaned, and moved to the next site within a few days.


Oil and gas wastewaters, including hydraulic fracturing flowback and produced water, contain a mixture of naturally occurring water constituents and many organic and inorganic additives. The composition of wastewater vary significantly depending on the region and type of operations. To obtain an optimum wastewater treatment process, the PEARL BLUE system employs two innovative treatment processes, electrocoagulation (EC)-hydro (H2) floatation and continuously cleaned nanofiltration (NF) to treat flowback and produced water.


Key Features:

  • High-quality treatment
  • Cost-effectively removes majority of scaling salts and operational boron
  • Patented technology
  • Can be monitored and controlled remotely
  • On-site laboratory facility
  • Uses electrocoagulation (EC)-hydro (H2) floatation and nanofiltration (NF) for optimum water treatment
