Abstract

The present study aims at solving the problem of stagnant water due to receiving of sewage water in a lake at Eastern Jeddah, using state of the art safe techniques. Samples were collected from the lake, then treated using magnetic fields with different intensities in two states, static and shaking, for 30 days. Hence, the physical and chemical properties for samples were measured, in addition to their bacterial content. In both cases of static and shaking, increasing the magnetic flux density caused water clearness, in addition to a relative increase in the pH value and a remarkable decrease in its odor and electric conductivity (EC). In addition, it was observed that lead ions and bacterial content decreased. The study shows that the increasing magnetic field intensity to the level used in this study, accompanied by shacking, is supplemented with the findings of the experiment. It also suggests that the magnetic field plays a major role in finding successful solutions for a lot of environmental problems, as the strong bonds that connect man to nature should be avoided.

Key words: Magnetic field, stagnant water, electric conductivity, pH, bacteria.
