Summary
Numerous processes in the chemical engineering are supported by the fluid flow at micro scale. As an example, aerobic granulation as promising technique in the biological purification of wastewater can be pointed out. Granular Activated Sludge (GAS), in comparison to Conventional Activated Sludge (CAS) has denser, compacter structure and higher biomass retention. Due to those properties GAS has a great application potential in biological purification of wastewater. However, granulation is a complex process and its mechanism has not been fully understood yet. Additional to biochemical, chemical and fluid dynamical factors in macro scale also characteristic microorganismic flow generated by cilia beats of Opercularia Asymmetrica which live on granules surface in micro scale should be taken into account during investigations of the granulation process. Thus, in the present work micro Particle Image Velocimetry investigations are carried out.
