LIQTECH INTERNATIONAL Business Summary

LiqTech International Inc. (LIQT) is a clean technology company specializing in advanced filtration solutions utilizing proprietary silicon carbide (SiC) ceramic membrane technology. The company generates revenue through three primary business segments: Water, Ceramics, and Plastics. The Water segment provides turnkey filtration systems for commercial swimming pools (QlariFlow™), marine scrubber water treatment, and industrial oily wastewater. The Ceramics segment focuses on the manufacture of SiC membranes and diesel particulate filters (DPF) for emission control, while the Plastics segment produces specialized machined and welded components. LiqTech operates in a competitive landscape alongside firms such as CERAFILTEC, PolyCera, Blue Foot Membranes, and Fuel Tech (FTEK). Within this market, LiqTech distinguishes itself as a niche leader in high-durability ceramic membranes designed for extreme thermal and chemical environments where traditional polymeric solutions often fail. Founded in 2000 by Damiano Zilio, LiqTech is led by a management team focused on commercial scaling and operational efficiency. Chief Executive Officer Fei Chen, appointed in 2022, brings extensive industrial experience from previous leadership roles at Grundfos and Haldor Topsoe. Supporting the executive suite is David Kowalczyk, who serves as both Chief Financial Officer and Chief Operating Officer, leveraging a background in global industrial finance from Hempel A/S and Novozymes. The company’s strategic direction is overseen by a Board of Directors chaired by Alexander J. Buehler, which recently expanded in February 2026 to include veteran finance executive Bob Wowk. Notable institutional support has included funding from the European Union, reflecting the company's alignment with global environmental and regulatory standards.
