Effect of a static magnetic field of 7Â mT on formaldehyde biodegradation in industrial wastewater from urea-formaldehyde resin production by activated sludge

► Effect of a magnetic field on wastewater treatment from amino resin production was measured. ► Exposure to MF increased formaldehyde removal by 20% in comparison to control. ► MF had a positive effect on COD removal and activated sludge biomass growth.
