Tangential flow membrane filtration

Tangential flow membrane filtration—microfiltration, ultrafiltration, nanofiltration, and reverse osmosis—for the industry.

We develop tangential flow (cross-flow) membrane filtration solutions that enable the separation, concentration, and purification of fluids with maximum efficiency, safety, and sustainability. Our expertise was first established in the dairy industry, where we pioneered the application of these technologies in cheese, yogurt, fermented products, and other dairy derivatives.

This foundation has allowed us to evolve toward the treatment of other complex agri-food liquids and explore new strategic sectors, always with an applied innovation and technology transfer approach.
