The capture and release of biomass using a high voidage fibrous filter (marked revision)

The capture and release of biomass in a high voidage fibrous microstructure: Mechanisms and shear stress levels

“…Together with the periodic flow reversal, this is sufficient to remove most of the deposited biomass as seen in Fig. 3 and reported in Bustnes and Mackley [3] from laboratory scale experiments.…”

“…By analysing the suspended solids concentration of the feed and effluent of the filter, the biomass accumulation in the filter could be calculated from a mass balance. More extensive results using this laboratory scale filter are reported in Bustnes and Mackley [3].…”

“…We have also explored the use of oscillatory fluid flow for the detachment and re-suspension of these biomass aggregates. We have briefly reported on visualisation studies relating to biomass capture in high voidage fibrous filters [5] and also described aspects relating to the hydraulic response of the system [3]. In this paper, particle capture mechanisms are identified and by using confocal laser scanning microscopy (CLSM), void fractions and surface areas are determined within the high porosity filter.…”
