With a membrane area of 10 m 2 and a 10-kD molecular weight cutoff, this new Flow-Cel module (photo) is optimally designed to filter protein-containing liquids with high solids content. The key feature of this cassette system is the ability to clean by permeate-sided backwashing. This increases the cleaning effectiveness and saves chemicals, time and manpower, says the manufacturer. Not just fermentation processes, but all protein-concentration applications with a high amount of solids — for instance cream cheese — can be handled. The Flow-Cel has been developed and tested together with operators in the biotech industry. The modular design, with different feed side height levels, allows the system to be modified according to the needs of each operator. Hall 4.2, Booth O15 — Microdyn-Nadir GmbH, Wiesbaden, Germany
