摘要：Under the external magnetic field, water(H2o) was exposed for different times to electromagnetic field that is generated by Aqua 4D device at flow conditions for twoflow rates as v0.18m/s and v0.6m/s at temperature 26.4°C. The pH and pH differences were investigated before and after exposure to the magnetization of water. It was found that EMF increases water pH and the amount of difference of the pH that shows a remarkable variation for a very small magnetization time. The variation of pH is proportional to the flow rate. The electromagnetic field generates ionization of the water molecules. Consequently, we noticed an increase in hydroxide ions (OH ) and the absorption of (H+) ions. It is also noted that the performance of a physical treatment water device depends on two parameters which are the exposure time of water to the electromagnetic field and the flow rates. The in flu ence of the electromagnetic field is manifested at the electrical conductivity, which was confirmed. This technical of treating water w ill offer many uses, such as increasing the pH of the water (to reduce the corrosivity of the water flow ), creating a local increase in the concentration of ions in the local volume of water, increasing water activity.
