Summary, etc. <p>Because of the development of novel applications, nanofiltration has attracted much interest in recent years. This research describes the removal of manganese ions from synthetic wastewater using a TFC NF-30 membrane. The effects of different operating parameters on heavy metal rejection were investigated, including feed concentration (20-60 ppm), applied pressure (5-8 kg/cm<sup>2</sup>), and pH (4-6). According to the current findings, the rejection coefficient for manganese ions increases with increasing pressure. The rejection coefficient reduces as the feed concentration of manganese ions increases at a steady flow rate.</p><p>The influence of pH was investigated, and it was discovered that when the pH rises, the rejection of manganese ions rises as well. The maximum measured metal rejection is reported to be 99.03 percent to 96.88 percent, for an initial feed concentration of 20 ppm and 40 ppm. The experimental data were fitted with membrane transport models such as combined-film theory-Spiegler-Kedem (CFSK) for the evaluation of the membrane transport parameters and mass transfer coefficient, k. For manganese ions, CFSK models were applied to estimate the experimental rejection (R<sub>OE</sub>) or actual rejection and modeling rejection (R<sub>OM</sub>) or observed rejection. In the CFSK model, the experimental and modeling rejection for manganese is roughly identical to ± 0.03.</p>
