Crossflow Filtration

Cross flow filtration is a process where the feed stream passes through the membrane. Using three streams, a pressure difference across the element drives water perpendicularly through the membrane, and the rejected particles travel along the membrane surface. The constant turbulence created along the membrane, prevents the accumulation of matter on the surface. The membranes run perpendicular to each other resulting in a pressure difference, driving water through the filter, while the particles retained (concentrate) continue to travel along the membrane surface.

Cross flow filtration is a clever way to filter liquids with a high concentration of filterable matter, such as beer, juice, and cider. It sweeps away larger molecules and aggregates that are retained on the surface of the membrane, preventing gel polarization. The membrane’s surface is continuously kept clean and free of accumulating substances which allows the equipment to perform continuously without the need to frequent cleaning. As a result, it can increase liquid yield, retaining the quality and taste of your beverage.
