Abstract


The effect of  magnetic field on the coagulation process and the possibility of reduce the coagulant dose with different cases of shedding the magnetic field on the two samples of water was studied, and the results showed that the magnetic field affects clearly and strongly on increasing the efficiency of removing the impurities from water (turbidity reduced from 662 NTU to 0.36 NTU and from 45.25 NTU to 0 NTU), and on reduction of the chemical coagulant (reduced optimal dose about 10 mg/L) by subjected water to magnetic field with optimal intensity in the  periods of rapid and slow mixing and sedimentation at the third bottom of the tank
