More Bio Fuel Filtration

This is the basic coffee filter that I have used to filter the Bio Diesel, I briefly cover how to make this biofuel filter from Coke bottles and coffee filter papers in the second video which I will post as soon as it uploads!

After making the Bio Diesel and separating the glycerin filtering allows you to get any last glycerin out of the Biodiesel before the wash phase of the biofuel manufacturing process. After the bio fuel is washed it will need to be filtered again before going into a fuel tank using the same coffee filter paper device to remove any methanol, soap or water.

In the photo below you can see that the bio diesel has filtered through the coffee papers and into the holding container below this process can take some time!

Below you can see the colour of the unwashed fuel, this still contains some methanol and excess Sodium Hydroxide so it will need to be washed and filtered again before it can go into a fuel tank.

How To Make Bio Fuel Out from Waste Vegtable Oil

Here is a short video explaining the process of taking filtered waste vegtable oil and turning it into Bio Fuel that you can use in your car.

How To Make Bio Diesel Using Coke Bottles - Filtering Waste Vegtable Oil

The first stage in making Bio Diesel from waste vegetable oil is the filtering of the oil to remove food debris a simple filtering system can be constructed from 3 Coca Cola bottles as shown in the photograph below.

The oil is poured in at the top and collected at the bottom a very simple process that can be performed anywhere you can find a 2 litre Coke Bottle and some waste oil!

This is a simple home made filter made out of 2 litre Coca Cola bottles. The waste vegetable oil (WVO) passes through a T-Shirt and then through a pair of tights, this removes any burnt bits of food that may be in the oil.

Above you can see the first part of the filtration process a simple T shirt is enough to remove most food debris from your waste vegetable oil however to be sure all the food debris is removed from the oil another filter is placed in series with the T shirt filter as shown below.

This second filtration of the waste vegetable oil has caught the debris, this photo was taken after filtering 20 litres.

The filtered oil is then collected at the bottom and can then be poured into another Coke bottle ready to be converted into Bio Diesel - BioD for short.
