Anti-scale magnetic treatment was applied to four calciumcompounds than are known to be scale formers. Aqueous suspensions ofthe compounds were cycled through a closed-system consisting of PVCpipe and a 1-L reservoir in the absence (control)or presence(test)ofa 2,000 gauss magnetic field. After a one-hour treatment period, thesuspensions were rapidly filtered, and aliquot portions of thefiltrate were acidified and analyzed for calcium content by atomicabsorption spectroscopy.
