The limitations of fossil fuel support on fulfillment of energy need in a sustainable andÂ environment friendly fashion has drove society to efforts of finding and developing fresh andÂ renewably resources. Biodiesel is one the renewable energy resource and shows environmentÂ friendly property, consist of alkyl of fatty acids monoester originated from vegetable oil or animal fat.One of important steps in biodiesel production is separation of glycerin from product. ElectrostaticÂ method has been proved in accelerating saturation of glycerin. However, several aspects still need aÂ careful assessment to acquire biodiesel production process with standard quality assigned. In thisÂ work, we designed an electrostatic separator of biodiesel from glycerin using waste cooking oil feed.Â The prototype was tested in several different voltages 12 Vdc, 20 Vdc, 30 Vdc and 33.5 Vdc. TheÂ result shows the highest voltage obtained is 33.5 Vdc, separation time 2 minutes 10 seconds havingÂ viscosity, water content and density i.e. 7.2139 cSt, 0.0321% and 0.85 g/mL respectively whereasÂ flash point increase to 1917 ï°C. The data confirmed that the product fulfills required standard value fordensity, water content and flash point.
