Investigation on Magnetic Field Usage for Urban Water Treatment

Abstract

The aim of this work was to investigate magnetic field (MF) usage for urban water treatment. Currently, the popular method of ground water purification includes water aeration and filtration, which are expensive and energy intensive. MF is not used for drinking water treatment but mostly for boiler and cooling water at industrial water plants or in farming for plant growth. The authors decided to test it at a small water treatment station in Poland. An MF generator was placed on the pipe between raw water intake and aeration. The results proved higher efficiency in water treatment, especially in hardness, turbidity, Fe, Mn and NH4 removal.
