Singapore-based Memsift Innovations entered into a technology transfer agreement with Ngee Ann Polytechnic pertaining to an innovative graphene membrane technology. The technology involves a breakthrough in membrane technology, featuring innovative graphene oxide-based hollow fibre ultrafiltration and nanofiltration membranes, developed over more than a decade of research and development.
The ultrafiltration technology utilizes a graphene oxide-block copolymer composite renowned for its exceptional chemical and thermal stability, making it ideal for harsh industrial applications. Its unique surface chemistry forms a protective water layer that effectively prevents fouling.
The nanofiltration technology employs a robust single-layer modified graphene oxide membrane with synthetic water channels, enhancing selectivity and permeability. This enables efficient molecular-level separation and differentiation between monovalent and multivalent ions.
These advancements promise superior performance and broaden potential applications across various industries, including textiles, agriculture, food and beverage, pharmaceuticals, pulp and paper, chemicals, microelectronics, semiconductors, and mining, marking a significant leap forward in membrane science and engineering.
Memsift Innovations is an emerging leader in membrane-based solutions, leveraging cutting-edge technology to address some of the most challenging industrial liquid waste treatment problems. Their state-of-the-art membrane distillation process and proprietary membranes, grounded in patented technologies, provide distinct advantages over conventional brine treatment and zero liquid discharge solutions.
The TS-30™ system employs a unique thermodynamic principle for thermal separation, substantially reducing industrial effluent treatment costs. Moreover, the advanced GOSEP™ Ultra and nanofiltration membranes are highly effective at separating various pollutants and monovalent ions from multivalent ions, even under harsh operating conditions.
As per the press release, Memsift is enhancing its product portfolio by acquiring next-generation graphene oxide membrane technology from Ngee Ann Polytechnic, further expanding its market offerings.
Dr. J. Antony Prince, Founder and CEO, Memsift Innovations said, “This is a highly anticipated milestone in our journey. The new graphene membrane technology offers several advantages over current state-of-the-art nanofiltration technologies.
