The Alfa Laval FESX nozzle bowl separators are designed for industrial fermentation applications and are available in many different sizes and configurations, each one designed and adapted for dealing with the widely varying separation tasks required. The FESX separators are nozzle bowl type units. This design makes them ideal for separating micro-organisms with high cell content, with or without solid impurities in the feed. In FESX separators, the cells are continuously discharged through nozzles positioned at the bowl periphery, enabling efficient handling of larger micro-organisms, such as yeast, with high cell concentrations.
