Abstract：

Ammonium nitrate solution containing trace calcium ion as feed water is filtrated with DK and DL polymeric nanofiltration membrane. Transmission of NH4NO3, rejection of Ca2+ and volumetric permeate flux are discussed as function of transmembrane pressure, tangential velocity and temperature. The results show nanofiltration membrane can reject at most 80% of Ca2+ meanwhile transmit no less than 90% of ammonium nitrate; rejection of Ca2+ first increases then decreases with higher transmembrane pressure; higher tangential velocity results in more rejection; volumetric permeate flux increases as transmembrane pressure or temperature increases. The results also show presence of NH4NO3 decreases the rejection of Ca2+.
