Integrating gravity-driven ceramic membrane filtration with hydroponic system for nutrient recovery from primary municipal wastewater

•Increasing periodic aeration rate reduced irreversible fouling of GDM.•Reclaimed wastewater was feasible for hydroponic vegetable cultivations.•Plants grown with treated water were comparable to those with fertilizer.•Shifting nutrient level and operation mode influenced plant growth profile.•Basil grown in reclaimed water had less health risk impact compared to lettuce.
