For high throughput, low underflow concentration operation, mechanical (compressive) support of the solids can be very small, providing that sludge funnelling is taken into account.
For low throughput, high underflow concentration operation hydrodynamic support of the solids can be small, and its neglect gives again fairly accurate results.
The measured polarization curves, constant-current discharging behavior and EIS spectra showed that the passive DMFC having the porous current collector yielded much higher and much more stable performance than did the cell having the conventional perforated-plate current collector with high methanol concentration operation.
In this paper, new small long-cycle PWR (Pressurized Water Reactor) cores for low boron concentration operation are designed by employing advanced burnable poison rods (BPRs) in which the BISO (Bi-Isotropic) particles of burnable poison are distributed in a SiC matrix.
The separation equations for the enrichment of heavy water in a batch-type thermal diffusion column have been derived for low-concentration operations.
Results show that the cell based on the composite structure yields the best performance during high-concentration operation.
The high-concentration operation requires the large methanol concentration gradient across the transport path from fuel reservoir to the catalyst layer, including fuel reservoir, fuel reservoir/current collector interface, current collector, backing layer and micro-porous layer.
MBR advantages and disadvantages, and process design to accommodate biological nutrient removal, high mixed liquor suspended solids concentrations, operation and maintenance, peak flows, and procurement are reviewed from the design practitioner's perspective.
Indoor aerosol dynamics, filter cost, and epidemiological models were combined to compare size-resolved indoor particle concentrations, operation costs, and monetized health benefits to occupants within an office building.
The present work determined the rheological behavior of anaerobic granular sludge obtained from a full-scale bioreactor at different solid concentrations, operation temperatures and particle sizes, and highlighted common features in flow and dynamic measurements.
