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.

Electrocoagulation (EC) is a wastewater treatment process in which aqueous pollutants can be removed by adsorption, entrapment, precipitation or coalescence during a coagulation step produced by electrochemically generated metallic species. When using Fe as the sacrificial electrode, Fe2+ and Fe3+ ions are formed. As Fe3+ species are paramagnetic, this property can in principle be used to facilitate their removal through the application of a magnetic field. In the present work we present a proof-of-concept for a combined electrochemical-magnetic method for pollutant removal. For this approach, the amounts of Fe2+ and Fe3+ produced in an EC cell at various voltages were measured by spectroscopic methods to confirm that Fe3+ species predominate (up to 84%). The effectiveness of the presence of a magnetic field in the precipitation of coagulants from a suspension was confirmed by monitoring the turbidity change versus time with and without exposure to a magnetic field, up to a 30% improvement.

It is significant to use different techniques to improve the overall efficiency of mine water treatment, because the utilization rate of treated mine water is low and the treating cost is high. According to the characteristics of water quality of coal mine water, the influence of the magnetic field on mine water treatment was studied in this paper in order to provide a reference for mine water treatment. It was found that magnetic field has effect on surface tension and electrical conductivity of mine water. When the magnetic field strength is less than 0.3T, the surface tension of the mine water decreases with the increase of magnetic field intensity, while the magnetic field strength is more than 0.3T, the surface tension of the mine water increases with the increase of magnetic field intensity. In the range of 0.0T ~ 0.5T, the mine water conductivity increases with the increase of magnetic field intensity and, as high as 14.8 ms/cm, then along with the increase of magnetic field intensity, the conductivity remains same. The influence of magnetic field intensity, amount of coagulant and magnetization time on coagulation were studied in this paper, and their effect were also investigated by Orthogonal test. The results show that when the magnetic field intensity is 0.35 T, magnetization time is 4 min and the amount of coagulant is 3 ml/L, the coagulation effect is the best. Under the condition, the mine water turbidity fell to 0.85 NTU from 200 NTU.
