The containerized "PureFlow^®" system was delivered to NESR in June 2024 and will be used at customers' sites in the Gulf Cooperation Council Countries (GCC) to demonstrate and document the efficiency of LiqTech's unique silicon carbide ceramic ultrafiltration technology in treating produced water to facilitate re-injection and beneficial reuse and meet current and future regulatory requirements. Longer term, the intention is to use the results and operational evidence from this pilot to design and implement full-scale commercial systems.

Fei Chen, CEO of LiqTech International, commented, "Water shortage is becoming an increasingly important topic for industrial applications across the globe. The oil and gas industry in particular understands how the ability to effectively treat produced water can play a key role in terms of overall sustainability, financial success and regulatory compliance. This pilot unit is of strategic importance to us as it provides the opportunity to demonstrate and document LiqTech's PureFlow® solution performance with its reduced OpEx and guaranteed quality. I am pleased with the progress LiqTech and NESR are making to expand our proprietary, next-generation water treatment technology to the Middle East region."

LiqTech currently has one full-scale commercial test unit for produced water in operation in the Middle East region that was deployed in May 2022 by a major oil and gas operator in the Middle East. This system has been successfully operating for more than two years now with over 99% of the feedwater passing through it being delivered back as clean brine/permeate water for reinjection. The quality of the clean brine/permeate exceeds the performance requirements originally defined by the end user. Furthermore, the system operates with a low amount of chemicals and demonstrating excellent energy efficiency.
