  • FLUID FILTRATION SYSTEM
    Publication number: 20230313117
    Abstract: An improved fluid filtration system is described. The system uses improved sensor assemblies to avoid the problem of biomass build up and reduce the holdup volume of liquid outside of the process vessel. It significantly enhances the performance, robustness and consistency of the filtration.
