Hydraulic permeability is defined as the inverse of resistance and is represented by the equation:
2.
The solute sieving coefficient and hydraulic permeability allow the quick assessment of the synthetic membrane performance.
3.
It also increases hydraulic permeability by allowing the mean pore size to approach the desired cutoff of the membrane.
4.
It was also discovered that there is a distinct relationship between the solute concentration deemed necessary to decrease transepithelial flow, and hydraulic permeability.
5.
Where J _ w is water flux, A is the hydraulic permeability of the membrane, ?? is the difference in osmotic pressures on the two sides of the membrane, and ?P is the difference in hydrostatic pressure ( negative values of J _ w indicating reverse osmotic flow ).
