LiqTech Secures First U.S. Commercial Pool Order for Three QlariFlow™ Systems

BALLERUP, Denmark, March 23 2026, - LiqTech International, Inc. (Nasdaq: LIQT), a leading clean technology company specializing in advanced filtration systems, has received its first commercial pool order in the United States for three QlariFlow™ ceramic membrane filtration systems.

The systems will be installed at the Weston County School District #1 Aquatic Center in Newcastle, Wyoming. The order was secured in collaboration with LiqTech's U.S. partner, Treatment Specialties - Powered by North American Filtration, and represents LiqTech's initial commercial pool deployment in the U.S. market.

QlariFlow™ systems are engineered around LiqTech's proprietary silicon carbide (SiC) ceramic membrane technology and are designed to meet the operational, regulatory, and space requirements of modern aquatic facilities. In public and institutional pool environments, QlariFlow™ delivers precise filtration, stable water quality, and reduced chemical consumption compared to conventional media-based filtration systems.

The United States is one of the world's largest markets for public and commercial swimming pools, including municipal, educational, and recreational facilities that operate under strict state and local health regulations. Entering this market with a reference installation marks an important step in LiqTech's strategy to expand its Commercial Pool business internationally through strong regional partnerships.

"We are pleased to secure our first commercial pool order in the United States in collaboration with Treatment Specialties," said Phillip Myllerup Aslerin, Business Development Director, Pool Systems at LiqTech. "This installation establishes an important reference for QlariFlow™ in the U.S. market and reflects the focused work of our commercial team to build partnerships and convert pipeline into orders. We see meaningful long-term opportunities for ceramic membrane-based filtration systems in regulated public pool environments."

With this order, LiqTech continues to execute on its Commercial Pool growth strategy by expanding into new geographic markets and increasing the global footprint of the QlariFlow™ platform.
