Reclaimed Water for Beneficial Use :: Developed in collaboration with Utah State University Research Foundation’s Space and Dynamics Labs, Purestream’s AVARA System reclaims produced and flow-back water at the well head through a unique vapor recompression process.

The resulting output stream is distilled water that can be put to beneficial use for field operations — non-detectable levels of TDS and TSS. Additionally, this technology can provide solutions to field source air emissions by capturing vent or flared gas to utilize as a fuel for the heat and energy required to operate. Large volumes of water are processed with very little energy cost because the energy expelled during the condensing phase feeds the evaporation phase. This integrated unit is thermally efficient (more BBL / BTU) and compact, via trailer mount or single container, providing greater field penetration and a reduction in water trucking and disposal costs. AVARA can be site-customized to process from 100 bbl/day to 100,000 bbl/day.

• Recycles high TDS water for beneficial reuse
• Reclaims produced / frac water at or near the well head
• Clean water product is put to beneficial use (fracing, agriculture)
• Can be site-customized to process from 100 bbl/day to 100,000 bbl/day
• Integrated unit is thermally efficient (more BBL / BTU)
• Compact unit is trailer mount or single container - allowing deeper penetration into the field
• Greatly reduces water trucking costs and dramatically minimizes disposal costs
• Low energy and capital cost / BBL water cleaned
• Final output stream can be run through final process to create potable water
• Resultant product is distilled water, clean air and power generation for environmental benefit

Utilizing a thermal membrane to separate produced water from the condensing chamber, steam is then pulled from the evaporation side of the membrane and is compressed by a blower into the condensing side of the membrane utilizing a unique, state-of-the-art technology designed specifically to minimize fouling issues. As the steam is compressed it condenses onto the thermal membrane and releases energy through the membrane into the evaporation side. This in turn increases evaporation, creating a loop that cycles the energy while evaporating water.
