That comes from here: [... when the processing's finished] 17. Allow to settle for one hour. 18. Optional: For easier washing: Drain off the glycerine. Measure off 25% of the total glycerine (including previously drained glycerine if you followed step 15) and mix with 10 milliliters of 10% phosphoric acid (H3PO4) for each litre of oil/fat processed. The mixing can be done with a wooden spoon in a plastic container. Pour the acidified glycerine back into the reactor and stir for 20 minutes, unheated. Allow to settle for at least six hours and then drain the glycerine fraction completely. http://journeytoforever.org/biodiesel_aleksnew.html Foolproof biodiesel process: Journey to Forever It's been there for a long time.
