in this article in order to consideration of the magnetic field influence on reducing of water and wastewater hardness experiments of treatment done in presence magnetic field at water quality laboratory Bu ali sina university . In this research magnetic field intensities of zero tesle as a witness 0.05 tesla , 0.75 tesla and 0.1 tesla , were examined. also it has chose amounts of water influent 4lit/h and 30lit/h. with doing examination by 3 times and analyze the results with SAS soft ware, have shown that , magnetic field changing at magnetic field intensity amounts of watewater influent, and also together influence there factors have significant effects at level of 99 percent on reducing of watewater hardness.
