Nowadays, industrial nanofiltration membrane technology is widely used, particularly when it comes to recovering and recycling water for preservation. This research is related to the processing of wastewater from one of the industrial areas in Indonesia into raw water using nanofiltration on a pilot scale. This research aims to identify the removal of nitrate and dissolved iron from industrial area wastewater through flow recirculation in nanofiltration and identify the effect of variations in wastewater concentration and variations in product recovery. The wastewater being treated is wastewater from an industrial area owned by PT. Jababeka Infrastruktur is composed of a ratio of 100% WWTP effluent, 9:1, 8:2, 7:3, and 6:4 between WWTP influent and effluent ratio. This study's membrane module employs a two-stage membrane system and a spiral wound with model specifications NF2-4040. Recirculation is used in the reactor to process the material and provide cross flow. The results of the study stated that variations in concentration made a significant difference to the removal of nitrate and dissolved iron (p value < 0.05), but variations in product recovery the opposite response. The processed water meets the raw water quality standards for nitrate parameters, but not for dissolved iron parameters at processed water concentrations of 7:3 and 6:4.
