Abstract
This study was conducted on nine wells water within Kirkuk city for the period 1st July 2015 until 13th June 2016 to assess the electromagnetic field's effectiveness in groundwater purification, where the study focused on the design apparatus with different electromagnetic fields accomplished by exposing the water to electromagnetic fields while the water is passing through the device. Electromagnetic water treatment process consists of two phases, the first by using different electromagnetic fields 1.4,1.7,1.9 Tesla with the stability of the water passage time 20 minutes through electromagnetic field and the second phase is consists of fixed electromagnetic field intensity 1.9 Tesla with change water retention time 5, 10, 20 minutes during the electromagnetic field . Study showed the effect of electromagnetic treatment on wells water hardness. The total hardness decreases at a rate of 18% when the field intensity 1.4 Tesla and 31% when the field intensity1.7Tesla , while the total hardness value decrease at a rate of 48% when the field intensity 1.9. The total hardness decreased at a rate of 15% when retention time 5 minutes and to 30% when retention time 10 minutes , while the total hardness decreased at a rate of 57% when retention time 20 minutes
