Impactful membranes for process fluids.

Help customers optimize their industrial water usage and align with regional standards using filtration membranes that reliably remove suspended solids.

Microfiltration membranes for process fluid filtration applications.

Many factors go into selecting the right membrane when developing filters for process fluid applications. You need assurance that the membrane inside your filter will consistently handle potential fluctuations of the process fluid to be filtered, while also maximizing operational efficiency. Increasingly, closed circuits are becoming more relevant, along with meeting cost savings and sustainability goals. High-performing membranes in filters resemble a key component in order to keep pace in achieving these goals. If finding the right membrane feels daunting, 3M can help you uncover a high-quality solution for your specific use case.


Whether your customers need pre-filtration for ultrapure water in their manufacturing processes, or they process wastewater, 3M membranes can help provide a finer degree of filtration. As an integral component in many fluid filtration processes, the microporous membranes help provide batch-to-batch consistency. Help end users process water more effectively and align with regional regulatory standards by incorporating a membrane developed by 3M filtration experts.
