LiqTech Advanced Oily Wastewater Filtration Selected by North Star BlueScope Steel – TradingView

LiqTech International Advances Sustainable Industrial Water Treatment with New Filtration System Order

Introduction

On June 25, 2025, LiqTech International, Inc., a leading clean technology company specializing in advanced filtration technologies, announced the receipt of an order for an advanced membrane-based filtration system. This system is intended to treat oily wastewater for North Star BlueScope Steel, a major steel producer in the United States.

Project Overview and Sustainable Development Goals (SDGs) Alignment

The new filtration system is designed to address recurring filtration challenges caused by high oil content and variability in wastewater quality. Scheduled for commissioning in the second half of 2025, this project supports several Sustainable Development Goals, including:

1. SDG 6: Clean Water and Sanitation – By improving wastewater treatment efficiency and water recovery, the project promotes sustainable water management.
2. SDG 9: Industry, Innovation, and Infrastructure – The deployment of advanced Silicon Carbide (SiC) membrane technology exemplifies innovation in industrial processes.
3. SDG 12: Responsible Consumption and Production – Enhancing water reclamation aligns with sustainable industrial production practices.
4. SDG 13: Climate Action – Efficient water treatment reduces environmental impact and supports climate resilience.

Technical Details of the Filtration System

• The system utilizes LiqTech’s robust Silicon Carbide (SiC) membrane technology, known for its durability in harsh industrial water conditions.
• This ceramic ultrafiltration system acts as a critical pre-treatment step to a downstream reverse osmosis system, enhancing process stability and water recovery efficiency.
• Crossflow filtration technology addresses the volume-in to volume-out challenge while adapting to fluctuating oil and turbidity levels in wastewater.

Statements from Key Stakeholders

• Fei Chen, CEO of LiqTech International: Emphasized the company’s commitment to supporting industrial water treatment challenges and contributing to customers’ operational efficiency and sustainability goals.
• Tony Grant, Services Senior Mechanic at North Star BlueScope Steel: Highlighted the importance of responsible water use due to the company’s proximity to the Great Lakes and expressed optimism about LiqTech’s technology enhancing water preservation efforts.
