Company Overview

LiqTech International, Inc. is a clean-technology and advanced materials company focused on the development, manufacturing, and commercialization of ceramic silicon carbide filtration technologies. The company operates primarily in the industrial filtration, water treatment, marine environmental compliance, and diesel particulate filtration industries. Its core products are designed to improve fluid purification, emissions control, and environmental compliance across industrial and maritime applications. LiqTech’s technology platform is centered on silicon carbide ceramic membranes and filtration systems that are valued for their durability, chemical resistance, thermal stability, and filtration precision.

The company’s primary revenue drivers include water treatment systems for marine scrubber applications, industrial wastewater filtration solutions, and aftermarket service and replacement membrane sales. LiqTech serves customers in sectors including marine shipping, mining, oil and gas, industrial manufacturing, and municipal water treatment. The company has positioned itself as a specialized provider of high-performance filtration systems capable of operating in harsh industrial environments where conventional filtration technologies may have lower efficiency or shorter operating lifespans. Originally founded in Denmark, LiqTech evolved from a materials technology business into a commercial filtration company focused on environmental and regulatory-driven applications.

Business Operations

LiqTech conducts operations through its filtration technology and water purification businesses, with manufacturing and engineering activities centered largely in Denmark. The company develops and produces proprietary silicon carbide ceramic membranes, diesel particulate filters, and complete filtration systems. Its major business activities include marine scrubber water treatment systems, industrial water treatment solutions, and aftermarket membrane replacement services. Revenue is generated through direct equipment sales, integrated filtration systems, recurring replacement components, and engineering support services.

The company’s operations are international, with customers across Europe, Asia, the Middle East, and North America. LiqTech controls proprietary membrane manufacturing technologies and related intellectual property associated with silicon carbide ceramic filtration. Historically, marine exhaust gas cleaning systems represented a major application area due to tightening International Maritime Organization emissions regulations. The company has also expanded into industrial wastewater treatment and oil and gas filtration applications. LiqTech has maintained partnerships with marine system integrators, industrial engineering firms, and environmental technology providers to support deployment of its filtration systems in commercial installations.

Strategic Position & Investments

LiqTech’s strategic direction has focused on expanding recurring revenue streams through aftermarket membrane sales and increasing penetration into industrial water treatment markets beyond marine scrubber systems. The company has emphasized operational efficiency, commercialization of higher-margin filtration applications, and diversification away from dependence on cyclical marine demand. Management has also highlighted growth opportunities tied to stricter global environmental standards governing industrial discharge, wastewater treatment, and emissions reduction.

The company has invested in scaling manufacturing capacity for silicon carbide membrane production and enhancing system integration capabilities. LiqTech has pursued product development initiatives involving advanced membrane filtration for difficult wastewater streams, including oily wastewater and industrial process fluids. Its technology portfolio positions the company within broader environmental infrastructure and sustainability markets, particularly in sectors requiring high-performance filtration under chemically aggressive or high-temperature conditions. Public filings and company disclosures indicate continued focus on industrial process water treatment and long-term recurring service revenue opportunities.
