LiqTech International, Inc. announced that it has received a flagship order from National Energy Services Reunited Corp. (NESR). The order is for a commercial pilot unit for the filtration of oil & gas produced water that will be used and tested for NESR customers in the Gulf Cooperation Council Countries (GCC).

LiqTech signed a partnership agreement with NESR in November 2022 and have since then worked actively towards commercializing LiqTech's produced water treatment filtration solution for re-injection and beneficial reuse across a range of countries in the Middle East, Northern Africa and Southeastern Asia. The containerized pilot system that NESR has acquired will be used at customers' site 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. LiqTech already has one commercial test unit for produced water in operation that was deployed in May 2022 by a major oil & gas operator in the Middle East.

This system has been successfully operating for nearly 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.
