A robust solution scheme for the basic flux and continuity equations is used to describe filtration and expression.
The numerical model for unified filtration and expression seems promising to further improve the understanding and control of dewatering of biological sludges as well as other solid/liquid suspensions.
The model starts from two existing models, each describing a part of the process [Iwata, M., Igami, H., Murase, T., 1991. Analysis of electroosmotic dewatering. Journal of Chemical Engineering of Japan 24(1), 45 50; Sørensen, P.B., Moldrup, P., Hansem, J.A., 1996. Filtration and expression of compressible cakes. Chemical Engineering Science 51 6), 967 979].
Current evidence indicates that both filtration and secretion are essential to hydrogen ion excretion and that both proximal and distal convoluted tubules are involved.
Therefore, in the current study, we employs diabetic nephropathy model to investigate the effects of Yishen capsule on proteinuria, glomerular filtration and podocalyxin expression in the kidney.
Experiments in both filtration mode and backwashing conditions for a wide range of superficial velocities were carried out.
In this study, a novel dual-functional protecting material with both OP filtration and degradation functions was designed and fabricated.
Both gel filtration and the fluorimetric analysis confirmed its monodispersed structure (Fig. 3).
Bisphosphonates are cleared by the kidney both by filtration and active proximal tubular secretion.
