The research considers the influence of permanent axisymmetric focused magnetic field on iron impurities in the water. The key attention is provided to determining (from experimental results) of mathematical model of water deferrization process by magnetic device. The deferrization efficiency has been chosen as the parameter of optimization, and the water flow rate and the part of waste – as the main factors of the experiment for research of water purification by axisymmetric focused magnetic field. During the experiment the total iron in water was reduced from 1.10 to   0.28 mg/dm3 and from 0.62 to 0.23 mg/dm3, turbidity – from 5.91 to 0.88 mg/dm3. Determined regression model of efficiency of water deferrization by focused axisymmetric magnetic field is adequate to Fisher’s F-test at the flow rate 0,14-0,40 m/s and the part of waste 0,10-0,35. The difference between regression curves and the experimental points is 2.57 %. To calculate the maximal effectiveness of water deferrization the regression model was reduced to canonical form, and additionally the regression equation was solved by iteration. Thus the maximal efficiency of water deferrization by magnetic device was 0.777 at the flow rate 0.31 m/s and the part of         waste 0.10.

Keywords: water deferrization, magnetic field, efficiency of purification, model.
