Abstract

Experimental design with a magnetic strength of 0.55 Tesla, a flow rate of 1.84 ml/s, 6 paired of non parallel magnets, with pH less than 7 showed that the concentrations of BOD, NH3-N, COD and SS were decreased up to three times using the settling test compared to typical treatment. The percentage of SS removal was 85.40 compared to 29.92 with-out magnet, so as BOD was 41.54 compared to 17.54, COD was 43.43 compared to 25.26 and NH3-N was 60.99 com-pared to 27.15 without magnet. This study concluded that magnetic technology had the potential to be used to further increase the efficiency of domestic sewage treatment by increasing the removal of suspended particles.
