The use of settling tanks to separate the different solids and liquids that will be used for the Biodiesel. In this Biodiesel project, two settling tanks will be used. One for the solids and one for the liquids. In a settling tank, the substance(s) with the highest density will sink to the bottom of the tank, while the less dense materials will stay higher. Through this process, the chemical mixtures that will be used for the biodiesel will be separated from each other. The denser chemicals will be separated from the less dense chemicals, and pure substances can be obtained.
