Energy-saving by recovery of value-added materials from complex dispersions by using semi-permeable membranes has been proved world-wide. The effect is related to fundamental knowledge of fluid flow and mass transfer in complex fluids close to membrane interfaces. Innovative biotechnologies for value-added products such as exopolysaccharides or antioxidants benefit by such explorations in preserving the biological activity of the target components. The paper presents a solution of theoretical model of a stirred tank reactor (STR) Biostat equipped with membrane immersed in a non-Newtonian model solution of exopolysaccharide, e.g. glucomannan and biomass. CFD methodology is employed to reveal original data on shear deformation rates and shear stress at the membrane interface, as well as to predict the average mass transfer coefficient related to the boundary layer at the membrane surface based on the flow information obtained. The results are compared with similar data reported for conventional systems with different impeller and systems with external membranes.

Manufacturing Operations Management (MOM) systems as central information and data hub play a very important role for an easy and seamless transition to Industrial Internet of Things (IIoT) applications. IIoT is mainly used in the context of Industry 4.0, that pursues the organization and management of value-added processes in the manufacturing industry with means of digitalization. The main aim of the proposed paper is to suggest some modifications to the IEC 62264 based models and architectures using RAMI 4.0 reference architecture in order to follow the basic principles of IoT and achieving the main advantages of IIoT.
