 Asahi Kasei has launched a membrane-based system designed to produce Water for Injection (WFI), a sterile water essential for injection preparation, as a sustainable alternative to traditional distillation. Developed with Microza™ hollow-fiber membrane technology, known for high performance in water and liquid filtration, this system minimizes steam generation, cutting both CO2 emissions and operational costs.
Widely respected in the pharmaceutical industry, Microza™ membranes deliver efficient filtration and robust technical support, establishing them as a preferred solution for pharmaceutical water applications. The WFI system employs steam-sterilizable ultrafiltration membranes, compactly designed for ease of use and enhanced operational efficiency. Compared to distillation, this membrane process eliminates the need for cooling and condensation steps, streamlining production and boosting water quality. By transitioning to membrane-based filtration, Asahi Kasei aims to offer the pharmaceutical industry a reliable and safer WFI production method that lowers emissions and maintains a steady supply.

 Water purification has become a crucial priority as the global demand for clean water rises amid growing scarcity. The United Nations has highlighted the urgent need to address water pollution, leading researchers at NYU Abu Dhabi (NYUAD) to develop an innovative, microwave-assisted approach for synthesizing a new type of membrane that efficiently filters contaminants. This technique, one of the fastest available, creates covalent organic framework (COF) membranes within minutes—an advancement that is vital for effective wastewater treatment. The membrane’s dual-surface design, featuring one superhydrophilic and one near-hydrophobic side, enables highly effective removal of pollutants such as oils and dyes, while its antibacterial properties contribute to durability and long-term functionality.
The study, titled "Tunable Wettability of a Dual-Faced COF Membrane for Enhanced Water Filtration" and published in the Journal of the American Chemical Society, was led by Professor Ali Trabolsi with researchers Farah Benyettou and Asmaa Jrad. Their method allows precise control over membrane thickness and surface characteristics, optimizing it for a variety of water contaminants without additional modifications. These COF membranes outperform traditional polymer membranes by delivering higher water flow rates, effective oil removal, and resistance to organic fouling. This breakthrough offers a more accessible, efficient solution for water purification, representing a significant advancement in sustainable water treatment technology.
