Characterization of flux-dynamic filtration

Flow filtration is one of the most common techniques for separating solids from liquids or gases. Innovation in wine filtration is evolving towards more delicate and selective systems, developing plant solutions capable of improving the stability and clarity of wine without affecting its sensory quality. The ability to dynamically adjust the filtration process according to the characteristics of the wine is one of the most stimulating challenges for modern oenology. Research is focusing on new technologies, such as the MMRHybrid system presented here, which open up interesting prospects for a future in which quality, efficiency and sustainability can coexist.

Flow-dynamic filtration is introduced and described in this module through a series of four complementary presentations aimed at redefining the concept of filtration in a modern key, with the aim of improving its effectiveness, protecting the organoleptic quality of wine as much as possible and defining some solutions suitable for improving the process in terms of environmental sustainability. Dr Riccardo Rossini (Enologica Vason) starts with a description of current practices and develops some reflections on market needs and the relevance of the project presented.

Professor Andrea Zattoni (University of Bologna) defines a new vision based on analytical evidence obtained through an advanced scientific approach: an innovative analytical method for the study of colloids, focusing on its advantages over traditional methods, which paves the way for a more precise understanding of the phenomena involved in filtration.

Through a comparison of different filtration systems, oenologist Federico Giotto (Giotto Wine Listeners) illustrates the principles of flow-dynamic filtration with reverse flow capillary membranes (Outside-In). The results obtained are analysed in relation to the sensory quality of wines, with case studies and practical implications.

Finally, engineer Marco Marconi (R&D Manager – JUCLAS) outlines the possibilities of transferring research data into concrete, plant-based solutions. An essential but comprehensive description of the technical characteristics of the developed system (MMFHybrid), its operating modes, and its application benefits in comparison with the most widely used and most suitable filtering technologies in the world of wine.
