Effect of static magnetic field on the efficiency of granular sludge development for pharmaceutical wastewater treatment

The effect of static magnetic field (SMF) on the development of granular sludge was evaluated in sequential batch reactor (SBR) system under alternating aerobic and anaerobic condition fed with pharmaceutical wastewater which is categorized as a high strength wastewater. The magnetic field intensity...
