LiqTech Secures Largest QlariFlow™ Pool Project to Date in Den Helder Through Partnership with Lotec

BALLERUP, DENMARK, May 19, 2026 /⁨EINPresswire.com⁩/ – LiqTech International, Inc., a clean technology company specializing in advanced ceramic filtration solutions, today announced its largest commercial pool project to date with the installation of five QlariFlow™ systems at Aquacentrum Den Helder in the Netherlands. The project has been secured in partnership with Lotec, a specialist in commercial pool engineering and water treatment solutions and LiqTech’s exclusive distributor in the BENELUX region.

The project includes five QlariFlow™ systems and two AutoCIP units, incorporating a total of 56 silicon carbide membranes. The first three systems were installed in January 2026, with the remaining systems scheduled for installation in August 2026.

Aquacentrum Den Helder is a municipal aquatic facility where space constraints and limited access required a compact and adaptable filtration solution. QlariFlow™ was selected for its ability to integrate within these constraints while maintaining high filtration performance and operational reliability.

“This project demonstrates how QlariFlow™ can be deployed in complex pool environments where footprint and system accessibility are critical,” said Phillip Myllerup Aslerin, Business Development Director, Pool Systems at LiqTech. “Our ceramic membrane technology enables a compact and modular system design while maintaining consistent filtration performance and operational stability. This project reflects our focus on scaling the commercial pool business through larger system deployments.”

The partnership with Lotec has been instrumental in delivering the project. Under a formal distribution agreement, Lotec holds exclusivity for LiqTech’s pool solutions across the BENELUX region and provides system design, engineering, and project execution.

“Our partnership with LiqTech introduces ceramic membrane filtration to a wider range of commercial pool operators in the BENELUX region,” said Raymond Visser, CEO, Lotec, and Erik Büter, Sustainability Specialist, Lotec. “Facilities such as Aquacentrum Den Helder require solutions that address physical constraints while meeting performance requirements. QlariFlow™ meets these requirements, and we expect continued adoption across municipal and commercial projects in the region.”

LiqTech’s QlariFlow™ systems are based on silicon carbide ceramic membrane technology, delivering precise filtration and stable water quality while reducing reliance on traditional chemical-intensive processes. The system is designed to meet the operational and regulatory requirements of public and commercial pool environments and to support efficient long-term operation.

The Den Helder project reflects adoption of advanced filtration technologies in municipal aquatic infrastructure, where operators are prioritizing system performance, operational efficiency, and reliability. Across the BENELUX region, this shift is driving demand for compact, high-performance filtration systems in both new-build and retrofit projects.

Building on this, LiqTech recently secured its first commercial pool order in the United States, with three QlariFlow™ systems to be installed at the Weston County School District #1 Aquatic Center in Newcastle, Wyoming. The order was secured in collaboration with Treatment Specialties, Powered by North American Filtration, LiqTech’s U.S. pool partner. The United States represents one of the world’s largest markets for public and commercial swimming pools, and this installation marks LiqTech’s first entry into U.S. institutional aquatic infrastructure, establishing an important reference for the QlariFlow™ platform in a highly regulated market.

Most recently, LiqTech secured a record order for 10 QlariFlow™ systems at the Plumpton Aquatic and Leisure Centre in Victoria, Australia, surpassing the scale of the Den Helder project. Delivered in collaboration with Waterco Limited, the all-electric facility is targeting 5 Star Green Star certification and is expected to become Australia’s first community aquatic centre to use LiqTech ceramic membrane filters, further demonstrating growing global demand for QlariFlow™.

Across the Netherlands, the United States, and Australia, LiqTech is converting a growing international pipeline into reference installations, each reinforcing the commercial viability of QlariFlow™ in regulated public and institutional aquatic environments. With regional partnerships in place and a track record of successful deployments, LiqTech is well positioned to accelerate adoption of ceramic membrane filtration in commercial pool markets globally.
