Osmotic pressure

In this paper, the viability of using micellar draw solutions (DS) for Forward Osmosis (FO) is presented for the first time. Above the critical micelle concentration (CMC) and the Krafft temperature (Tk), the monomers in a surfactant solution aggregate to form micelles, resulting in a relatively cons

Permeation experiments of aqueous solutions of diprotic amino acids (L-glutamine and glycine) were carried out with numerous commercial polymeric nanofiltration (NF) and tight ultrafiltration (UF) membranes. The aim of this study was to determine the permeate flux and the amino acid rejection as a f

The paper deals with a novel solar powered water desalination technique based on direct osmosis process. The separation is driven by natural osmosis, which does not require external pumping energy as in the reverse osmosis process. Therefore, the specific power consumption of the desalination proces

A theoretical study is developed for the modelling of mass accumulation from the polarised layer to the formation of a deposit. Concentrated suspension properties are accounted for through a solid pressure corresponding to osmotic pressure in the suspension and to compression resistance in the depos
