Study of Non-Uniform Electrical Field for Splitting of Colloidal Particles from Waste Water

: This study is about the non-uniform electric field (Dielectrophoretic) with sinusoidal current for splitting of colloidal particles from wastewater of Alborz Carpet factory in Babolsar. Then this method was compared to the other methods. The study is considered the effect of temperature, time, and voltage on the separation efficiency of colloidal particles. The results show that the non-uniform electric field method can be one of efficient methods for removal of colloidal particles from wastewater. Turbidity was measured by turbidity meter (FNU=Formazine Nephelometry unit) in the present study. Using the non-uniform electric field with 7500-volt intensity and 50-hertz frequency and 40 degree centigrade temperature, the splitting is done 96 %.
