Filter Module Scalability


Guide to Process Scalability for Spectrum Hollow Fiber Modules


Hollow Fiber Filter Scalability Due to the consistent flow dynamics between hollow fiber membranes, Spectrum filters lend themselves to direct volume and surface area scalability by increasing the number of fibers while maintaining the same fiber flow path length. This allows you to easily transition from R & D (MicroKros®, MidiKros®, MiniKros® Sampler) to Process Development (MiniKros) and on to Production (KrosFlo®). Module total length (TL) and fiber effective length (EL) are shown below.
