Memsift Innovations Pte Ltd has partnered with the Singapore Institute of Technology (SIT) to develop advanced chemical-resistant nanofiltration (NF) membranes. These membranes aim to recover valuable chemicals from spent acids and bases in wastewater generated by the microelectronics and semiconductor industries, offering a more sustainable solution compared to traditional methods.
Memsift Addresses Environmental Challenges in the Semiconductor Industry
The semiconductor industry produces large volumes of wastewater containing spent acids, bases, and heavy metals. Current treatment methods, such as neutralization and incineration, are not only costly but also energy-intensive and environmentally harmful. With increasing regulatory pressure, there is a growing need for efficient and sustainable waste management solutions.
Dr. J Antony Prince, CEO of Memsift Innovations, highlighted the significance of this initiative:
“This collaboration addresses the urgent need for innovative liquid-waste treatment solutions that prioritize sustainability and circular economy principles.”
SIT and Memsift Develop Cutting-Edge Membrane Technology
The research focuses on developing NF membranes with high chemical resistance, selective permeability, and enhanced durability. By incorporating advanced materials such as functionalized graphene and hybrid organic-inorganic nanomaterials, these membranes will be able to withstand the harsh chemical environments of semiconductor wastewater. They are designed to recover more than 90% of valuable chemicals, such as those used in photoresist stripping baths.
The membranes will undergo rigorous testing using advanced characterization techniques and will be demonstrated at a global microelectronics manufacturing facility in Singapore by the end of 2025.
Memsift’s Technology Supports Sustainability and Industrial Efficiency
The adoption of these NF membranes is expected to provide several benefits, including:
- Reduced waste volumes, lowering disposal costs
- Optimized energy consumption, improving operational efficiency
- A more sustainable approach to wastewater treatment, meeting stricter environmental regulations
Beyond the semiconductor sector, these membranes could also be applied to other industries requiring resource recovery from high-strength wastewater streams.
SIT’s Role in Academia-Industry Collaboration
SIT will contribute expertise in membrane design, formation, fabrication, and performance analysis. This partnership aligns with the university’s mission to bridge academic research with real-world industrial applications.
Associate Professor Zuo Jian, leading the research team at SIT, emphasized the broader impact of this initiative: “By combining our research capabilities with Memsift’s industry experience, we are developing advanced solutions for high-value manufacturing sectors while equipping students with hands-on skills to drive real-world impact.”
As part of the collaboration, at least three SIT students from the Pharmaceutical and Chemical Engineering programs will participate in polymer processing, membrane fabrication, and process analysis, gaining valuable industry experience.
Memsift and SIT Paving the Way for Sustainable Waste Management
This collaboration strengthens Memsift Innovations’ position as a key player in sustainable water management. The new NF membrane technology is set to transform liquid-waste treatment in the semiconductor industry, offering an efficient and environmentally responsible solution for resource recovery.
