Two variational principles control isotonic osmosis and reverse osmosis: the principle of least dissipation of energy referring to a definite time integral and the principle of least constraint referring to the stationary (extremum) value of a volume integral.An extended form of the Nernst–Planck equation resulting from the time variation has been ...

Concentration of antibiotics by reverse osmosis
Biotechnology and Bioengineering, 1977AbstractReverse osmosis is shown to be a viable process for the concentration of highly labile antibiotic solutions. Mathematical n10deJs of antibiotic inactivation by chemical and biological contamination are proposed and correlated with experimental data. Procedures for obtaining high antibiotic recoveries are discussed.

Why polyamide reverse-osmosis membranes work so well
Science, 2020Inhomogeneities in membrane thickness and density promote water transport Desalination technology leaped forward with the development of interfacially polymerized reverse osmosis (RO) membranes patented by Cadotte in 1981 (1).

AbstractThe nonlinear problem of reverse osmosis in annular conduits is solved by a series expansion method which is very accurate in the diffusion entrance region near the inlet of the membrane section. It is found that polarization at the outer membrane surface is significantly greater than at the inner wall.In the diffusion entrance region, for the ...

Desalination by Reverse Osmosis
2017This chapter deals with the main techno-economic and environmental issues involved in assessing the sustainability of RO membrane technology for water desalination. The technical and economic aspects of desalination plant design and operation are reviewed, focusing on the key parameters of specific energy consumption (SEC) and product water unit cost ...
