Organic solvent nanofiltration is an emerging technology made possible by the recent development of solvent resistant nanofiltration (SRNF) membranes. These membranes have many potential applications from continuous operation over many months in refinery systems [1,2] to shor ...

In the present study the application of the nanofiltration process was investigated mainly in the retention of color and chemical oxygen demand (COD) present in textile industry wastewater.... industry wastewater. Nanofiltration experiments were carried out in a pilot unit, operating in crossflow. Three different types of spiral wound membranes, DK 1073, NF 45 and MPS 31 were used simultaneously in the same unit. The results of the tests showed that for color retention, the values wer ...

... concentrations and they are therefore difficult to be treated. In this work the effluents from the cotton textile industry was treated by nanofiltration membrane in order to reduce the quantity of the disposed water and at the same time to reuse the treated water. A detailed investigation of the... high recoveries and feed concentrations. An excellent performance for the TRISEP (4040-XN45-TSF) nanofiltration membrane was found. This type of membranes can achieve complete decolorization of the cotton dye effluents and they reduce the total salt concentration more than 72%. They practically zer ...
