The rapid increase of human population accompanied by industrial growth and rising standards of living has resulted in heavy demand for water across all sectors. So, treated wastewater could be an unlimited and stable alternative for water supply to use in irrigation and industry and plays an important role to achieve sustainable urban development. Nowadays, finding an appropriate wastewater treatment & reuse method is one of the important issues which many research has been conducted in this field. The aim of this study was to compare the treated wastewater (industrial) by biological method compared to the nanofiltration method and determine more suitable method for industrial wastewater treatment. Thus, BOD5 of industrial wastewater was used for this purpose and the appropriate method was chosen by calculating the percentage and percentage of this parameter as well as analyzing the significance of the difference between the results of the two methods used by SPSS software. The nanofilter used in the study was made from carbon-neon and the pressure of its desired performance has been 10 times and the diameter of the stomata is 50-80 nm. Also, all experiments were performed weekly for a period of 11 weeks in Najaf Abad wastewater treatment plant. The results showed that the mean BOD5 = 6.87 mg / L measured by nanofiltration method while the mean BOD5 is 9.91 mg / L by biological method. According to the results, the nanofiltration method is more effective than the biological method. Nanofiltration method is suggested to prove the superiority and other water quality parameters are also tested.
