Seattle, Washington Patent of the Year – 2024/2025
Membrion Inc. has been awarded the 2024/2025 Patent of the Year for its breakthrough in water purification technology. Their invention, detailed in U.S. Patent No. 12087982, titled ‘Ceramic anion exchange materials’, introduces a novel class of silica-based membranes designed for efficient ion removal in harsh industrial environments.
Membrion’s patented technology utilizes silica-based ceramics to create anion exchange membranes with tailored pore structures and chemical functionalities. These membranes incorporate quaternary ammonium groups covalently bound to the ceramic matrix, enhancing their ability to selectively transport negatively charged ions. The design allows for effective separation processes, making them suitable for applications like electrodialysis and wastewater treatment.
Unlike traditional polymer-based membranes, these ceramic materials offer superior chemical stability and durability, particularly in environments with extreme pH levels or oxidizing agents. This advancement addresses the limitations of existing technologies, providing a more sustainable and cost-effective solution for industries dealing with challenging wastewater streams.
By enabling efficient ion exchange in demanding conditions, Membrion’s innovation holds the potential to revolutionize water treatment processes across various sectors, including manufacturing, energy, and municipal services. This patent underscores the company’s commitment to developing cutting-edge solutions that contribute to environmental sustainability and resource conservation.
