Why is it necessary to filter the raw bio diesel?
Once the bio diesel has reacted and the glycerol has been drained off, the bio might appear clear enough to use. It will however still contain small amounts of un-reacted oil, methanol and soap. Cycling the raw bio diesel through the in-built resin filter for 4 to 6 hours will remove all remaining un-wanted elements, leaving a crystal clear product ready for testing. As a final level of filtering, we have also built-in a 10 micron bottle filter which is in the fuel dispensing line before the nozzle dispenser. This filter will take out any remaining water from the process.
