This work deals with the temperature effect on rejection of neutral and charged solutes by a nanofiltration membrane (Desal 5 DK of GE Osmonics). The experiments were conducted with a tangential Sepa CF cell with a flow velocity equal to 1.27 m/s. The pressure was varied form 5 to 15 bar and the tem

Retention properties of a nanofiltration ceramic membrane were investigated with single polyethyleneglycol (PEG) solutions and mixed PEG/inorganic salt solutions. The rejection rate of PEGs was found to decrease in the presence of ions. It was shown that the effect of ions on the retention of neutra

One of the most, but yet fully untapped potential areas of disposal from a technical and environmental angle is brine reject. Most of the RO plants can make best use of either 1st stage or 2nd stage brine depending on its end-use and the inter-stage salinity thereof. While dealing with disposal scen
