Reduction of COD for the wastedater from paper manufacturing process was attempted by magnetic separation technique. FeSO4 and KOH solution were added to the wastewater to recover the organic component by utilizing the co-precipitation and oxidation processes to give the magnetism. It is found that COD value was reduced after magnetic separation.
