purification process in affect

Today in class we started the purification process. We used many materials during this process we used a strainer net, cheese cloth, flask, and a bucket. First we have to purify the oil before we start the process of making the oil. We use two buckets. Clean one bucket and put the strainer net over, than cheese cloth than another strainer net. This well help separate the food particles from the vegetable oil. The vegetable oil is used from our school cafeteria. After we pour the vegetable oil in the bucket we will than again repeat the process. Than we will pour it into flask.We did not get to this step today but than Fill 1/25 of the flask with water and pour the rest in with the pre-filtered vegetable oil. This well help the particles to dissolve or rise to the top. Than we will repeat the process in separating the particles with the buckets. After we will than begin the process of mixing the right chemicals so it will run on a diesel engine.
