Waste vegetable oil can be collected from numerous outlets, for example; cafes, public houses, restaurants, fish and chips shops - anywhere that uses vegetable oils for cooking. The waste produced can be used as a road fuel, but needs to be cleaned before use in a road vehicle. Waste oil contains impurities from food that have been cooked into it, water, meat, fats, etc. These need to be separated from the oil to make it ready for use. There are alot of different ways to clean oil, all variations on a theme; below is a widely used separation system which a lot of domestic users find best, speeding up the natural process of separation.

Dispensing WVO
| Step | Lid | Heater | Pump | V1 | V2 | V3 | V4 | V5 | V6 | V7 | V8 | V9 | V10 | V11 | Notes |
| Dispense settled oil | Lid can be on or off for this operation. |
The wvo goes into the drum via a 400 micron drum filter, it's then heated with the option of circulating to speed dewatering, it is then pumped into the storage drum via 20 and 5 micron filters. Most filters are rated at 0.8 bar so there is a bypass valve which ensures the oil is never forced through the filters. From the storage drum the oil goes through a 1 micron filter protected by the bottom bypass valve to the car/drums. A pipe and valve also connect the crud valve to the pump inlet so this can also be used to make biodiesel but it will need
an additional wet or dry wash tank. The methanol can be introduced before the pump and a pipe attached to the top of the sight tube
becomes the vent.
It will transfer to the wash/settling tank avoiding the filters and it utilises the clip top for sealing the processor.
An inline heater cannot be used with this design but an eductor or venturi could be added if desired along with a condensor but an additional vent outlet would need to be fitted to the lid.
You can dispense your wvo to the car/container via the delivery nozzle. When the trigger is released the oil is sent back to the tank by a bypass valve.

Safety Point
There is a float switch which cuts out the immersion heater at low oil level
Main Features
My aim was to make a self contained dual unit to which you can add extra storage drums/wash tank as needed but to also be affordable and portable. Also if either filter blocks the bypass valve will send the oil back into the main drum where it will just circulate in a loop. It is geared heavily towards filtering but can easily be used to process the unusable oil into bio

Note: When useing this filter system (YOU MUST DROP WATER & FATS) after heating and before pumping out, if not you run the risk of emulsification with newly settled oil and the crud layer zone water/fats mixing up.
