Human Wastewater Treatment by Superconducting Magnetic Separation Using a Bench Scale System

A physico-chemical process combined with electrocoagulation using iron electrodes, high gradient magnetic separation and electrochemical oxidation was investigated for human wastewater treatment using a bench scale system. Magnetically-seeded suspended solids and phosphorus in human wastewater were removed effectively at a flow rate of 100 L/h applying magnetic separation using a magnetic filter at 10 T. The electrochemical oxidation process reduced ammonium nitrogen (NH4-N) and chemical oxygen demand (COD) in effluent from the magnetic filter at a flow rate of 15 L/h. The results indicate that this physico-chemical process is effective treating human wastewater.
