Insights
LiqTech secures meaningful industrial order with North Star BlueScope Steel, demonstrating market validation for their specialized SiC membrane technology.
This order from North Star BlueScope Steel represents a significant commercial validation for LiqTech's silicon carbide (SiC) membrane technology in the industrial water treatment sector. The company is addressing a specific pain point for the steel producer - recurring filtration process upsets caused by high oil content and variable wastewater quality.
The technical differentiation of LiqTech's solution lies in its ceramic ultrafiltration system, which serves as critical pre-treatment for downstream reverse osmosis. Their SiC membranes are specifically engineered to withstand harsh industrial environments where conventional polymer membranes often fail. This creates a compelling value proposition for heavy industry clients facing similar challenges.
From an industrial application perspective, this implementation solves the common "volume-in to volume-out challenge" that plagues crossflow filtration systems. The ability to maintain consistent performance despite fluctuating oil content and water turbidity is particularly valuable in steel production, where process water conditions can vary significantly.
While the press release doesn't disclose the financial terms, this order aligns with two important industry trends: increasing water reuse requirements in industrial operations and stricter discharge regulations. For North Star, located near the Great Lakes, water stewardship is both an environmental priority and likely a regulatory necessity.
The scheduled commissioning in H2 2025 suggests this represents near-term revenue for LiqTech, with potential for similar implementations across the broader steel industry as sustainability practices become standardized. This appears to be part of LiqTech's strategic focus on industrial water treatment applications where their ceramic membrane technology offers distinct advantages over conventional solutions.
BALLERUP, Denmark, June 25, 2025 (GLOBE NEWSWIRE) -- LiqTech International, Inc. (Nasdaq: LIQT), a leading clean technology company that manufactures and markets highly specialized filtration technologies, today announced it has received an order for the delivery of an advanced membrane-based filtration system to treat oily wastewater from North Star BlueScope Steel, a major U.S.-based steel producer.
The system, designed to resolve recurring filtration process upsets caused by high oil content and variability in wastewater quality, is scheduled to be commissioned and begin operation in the second half of calendar year 2025.
The wastewater filtration solution uses LiqTech’s robust Silicon Carbide (SiC) membrane technology designed to withstand harsh industrial water conditions and deliver consistent, high-quality filtration. This ceramic ultrafiltration system will serve as a critical pre-treatment step to a downstream reverse osmosis system, enhancing overall process stability and water recovery efficiency.
While crossflow filtration is the most sustainable wastewater treatment process, it comes with a major volume-in to volume-out challenge. LiqTech’s ceramics-based system addresses this challenge while adapting to ever-changing oil and turbid water quality.
Fei Chen, CEO of LiqTech, commented: “We are proud to support North Star BlueScope Steel with our proven solution to a complex challenge. This project demonstrates our growing traction in industrial water treatment and our ability to contribute meaningfully to our customers’ operational efficiency and sustainability goals.”
Tony Grant, Services Senior Mechanic, North Star BlueScope Steel, added: “North Star’s proximity to the Great Lakes keeps responsible water use top-of-mind for our entire team. We are excited to see how LiqTech’s technology will further enable our water preservation efforts through enhancements to our water recovery technology.”
The addition of advanced wastewater pre-treatment filtration supports North Star’s broader water reclamation initiatives and reflects a growing trend in the steel industry toward more sustainable water management practices.
