Abstract
The clarity and purity of water was examined by using electrocoagulation process. Aluminium electrode was used throughout this study as an anode. The anode dissolves introducing Al3+ into turbid water. Different factors; temperature, NaCl concentration, particle size, the amount of clay and the source of water which affect the efficiency of the electrocoagulation were studied. It was found that there is a positive relation between the current density and the removal of clay dispersed particles. The same relation was found between the suspended clay particles and the turbidity of water. The turbidity in the supernatant becomes higher in the fine than the coarse particles at constant energy consumed. The clarity of water decreased with increasing the temperature from 303 to 323 K. The turbidity decreased with increasing NaCl concentration. The energy consumed for the electrocoagulation process was less for natural turbid water than for artificial turbid water. The advantage of this method is the possibility of simultaneous removal of the dispersed particles in a friendly and safe way.
