In the current study, a novel thin film composite nanofiltration membrane was prepared by interfacial
polymerization and evaluated for water softening. Its nanofiltration performance was evaluated by cross flow filtration
using NaCl (1 g/l) and MgSO4 (1 g/l) solution at 5 and 10 bars, 25 °C and 10 l/min. The morphological study was
investigated by SEM and AFM. In addition, Thin-film composite polyamide nanofiltration membrane was fabricated
using interfacial polymerization of piperazine with trimesoyl chloride (TMC) onto PES ultrafiltration membrane
prepared with immersion precipitation technique. A rough, dense was formed on the PES support membrane by
interfacial polymerization. The water permeability of composite membrane was 50 and 178 kg.m−2.h−1 at 5 and 10 bars,
respectively. Moreover, the rejection to the divalent salt MgSO4 (74 and 80%) was high compared to the monovalent
salt NaCl (55 and 59%).
