The document describes a cross-flow filtration system called "Cross-Flow for Wine" (FCW). It can be used at various stages of wine production for gentle mechanical and microbial filtration. The system uses polypropylene membranes and automatic reverse flow to filter wine more gently and efficiently compared to other cross-flow systems. It provides substantial time and cost savings over conventional methods while preserving wine quality. The modular system comes in various sizes to suit different throughput needs and automation levels.
