Does Magnetic Field Change Water pH?

Salt-laden waters pose major problems in the hydraulic field. Scaling problems can be troublesome for sanitary, potable and irrigation water networks. Also, irrigation water salinity is a major concern for agriculture, affecting crop productivity and yield. To alleviate some of these problems, various physical processes are put to the test such as magnetic processes. A laboratory experiment was conducted at the Laboratory of Natural Water Treatment of Borj Cedria Tunisia, to study the effect of different magnetic treatments (M1=3300 Gauss, M2=2900 Gauss, M3=5000 Gauss and Electromagnetic Em=900 Gauss) under two flow rate (0.03 and 0.06 letter/second) and two temperature (18 and 24oC) on water characteristics in order to observe the variation in the pH of water. The application of all magnetic field treatment showed slightly an increase in the pH of treated water compared to untreated water.
