Abstract
Described herein is an improved method for the fabrication and use in modifying the physicochemical properties of water, as in strong, high density gradient application. This new approach provides in situ devices capable of inexpensive and effective water modification and treatment. The underlying concept is based upon the use of fine particle super ferromagnets or super paramagnets dispersed in nonmagnetic media. These media can be materials such as brass, cellulose or a wide variety of ceramics. Nonaqueous applications include the removal of impurities from liquid polymer streams. Other applications involve pseudo polymers or fluids exhibiting weak inter- and intra molecular forces.
