|Abstract:||This study presents treatment of dye containing wastewater in a nanofiltration pilot plant using hydrophilized polyamide membrane of flat sheet module. Permeate flux (PF) decreased with time of operation due to concentration polarization. Effect of trans-membrane pressure (TMP) showed a quasi-linear increase in flux with increasing pressure. PF (1.44 × 10-6 m3/m2.s) at 5 kg/cm2 was enhanced as PF (1.62 × 10-6 m3/m2.s) at 10 kg/cm2. Flux increased considerably with increase in dilution of wastewater. Maximum PFs obtained with 5 fold and 10 fold dilutions were 3.95 × 10-6 and 7.06 × 10-6 m3/m2.s respectively. Substantial removal of colour (98.3%) was achieved with a marked reduction in COD (89%) and TDS (77.2%).|
