Purestream Services, LLC, announced the company's latest technology deployment of a thermally efficient wastewater treatment AVARA vapor recompression system at a commercial waste water disposal facility in Warren, Pennsylvania.
The AVARA system is now operating within a wastewater disposal and treatment plant's existing train of treatment technologies. The AVARA Vapor Recompression technology completes the overall water treatment process at the Warren facility, bringing the discharge water quality levels to regulatory compliance by meeting new discharge criteria in the state of Pennsylvania. The system treats about 2,000 barrels (84,000 gallons) of water per day.
AVARA is an innovative, patented, vapor recompression technology with an optimized, smaller footprint that easily integrates into existing plant and field operations. Purestream originally developed the AVARA project in partnership with Utah State University's Space Dynamics Research Lab scientists. The AVARA system includes state of the art thermal management processes, automated functions and remote monitoring capabilities. It is a robust system that consistently provides a clean, distilled quality, water effluent stream. This advanced vapor recompression process concentrates the waste stream for significant waste volume reduction. The AVARA technology has been commercially utilized for over four years in various onshore oil and gas wastewater operations. Current active AVARA deployments are operating in Arkansas, Texas, and Wyoming to treat produced and frac water in oil and gas operations for volume reduction, re-use and discharge. It has successfully demonstrated consistent ability to meet stringent NPDES discharge limitations in a number of applications.
"We are pleased to be transitioning AVARA technology into a broader market, which demonstrates the flexibility and reliability of vapor recompression," stated Neil Richardson, Purestream CEO. "AVARA is able to check-off a lot of boxes in waste water treatment including volume reduction, increased brine concentration, improving discharge quality and providing clean water for recycling and re-use."
In light of new EPA Guidelines released last month, Purestream also sees AVARA as a real solution for steam electricity power generation plants that are required to meet the new criteria for wastewater discharge in the coming years. Vapor recompression technology is effective in removing heavy metals, such as mercury, arsenic, selenium, nitrates and other pollutants to meet the new standards outlined in the EPA Regulations released in September. Clean distilled water from AVARA may be re-used in plant operations or discharged under regulatory authority. The system demonstrates outstanding capabilities as it integrates into existing water treatment operations and reduces volume by concentrating waste stream brine to higher levels than other technologies such as Reverse Osmosis.
Purestream continues to grow its business to provide innovative and cost-effective water treatment technologies and services to treat produced and frac water in the oil and gas field for re-use and discharge.
