Water purification, Water quality management
Properties and characteristics of colloidal systems are reviewed with a discussion of colloid systems to be found in natural and wastewaters. Current electric and magnetic field theory are reviewed and summarized to provide practical application of the theory to engineering problems in the environmental field. Literature of colloidal reactions to electrical and magnetic fields is discussed and reviewed to ascertain areas of potential application of electric and magnetic phenomena to natural and wastewater treatment systems having objectionable colloid suspensions. It is concluded that application of electrical fields (electrophoresis) does not currently hold much promise for practical applications in water treatment systems. However, and understanding of colloid systems and electrophoresis is strongly recommended for personnel involved in chemical treatment of waters. It is shown that there has been considerable research and many applications of magnetic field treatment of waters by the Russians, most analysis of which is performed in an empirical manner that tends to cloud the phenomena with an aura of mysticism. Practical applications of magnetic field phenomena to water treatment systems involving ferromagnetic colloidal suspensions appears promising and research into this area is recommended.
