STB-013 Lees Filtration

ees, the sediment found at the bottom of wine and juice tanks, can make up a significant portion of a winery's production volume. Recovering this residual product is a challenging filtration process, often done using Diatomaceous Earth (DE) filtration systems. However, these systems can introduce oxygen and require large volumes of filter aid, leading to increased waste and labor. In contrast, crossflow filter technologies like the SCEPTER® system offer a more efficient and robust solution for lees filtration. These systems use high-strength inorganic membranes that allow for high recovery rates and aggressive cleaning, ensuring long-term effectiveness and cost savings. The SCEPTER system works by pumping the contaminated feed stream into a membrane-lined tube, where clean liquid passes through the membrane while concentrated contaminants are collected for disposal.
