Abstract
Population growth and the need for sustainable urban development as well as lack of water resources due to the position of Iran in the arid and semi-arid zone and the occurrence of recent drought has seriously raised the importance of water scarcity. Nowadays, unconventional water resources are considered as one of the possible solutions to provide water supplies. Among different resources of unconventional waters, the use of wastewater as a sustainable resource for water scarcity management is considered as a strategic strategy. The aim of this study was to compare biological treatment method and nanofiltration method to remove sulfate from industrial wastewater. Thus, industrial wastewater of Najaf Abad treatment plant was used for this purpose and the experiments were carried out for 11 weeks and 11 replications. The appropriate method was chosen by calculating the removal percentage of various parameters and SPSS software was used to analyze the significance of the difference between the results of the two methods. According to the results, the percentage of sulfate removal in all experiments in the nanofiltration system was higher than the biological system and nanofiltration method is more reliable to remove sulfate. So, nanofilter system would be a good alternative for the biological system to reduce and remove sulfate in industrial wastewater.
