CHEMIPHASE pHCorrect68 should be added to the produced biodiesel once the glycerine layer has been removed and no filter aids have been added.
Sufficent pHCorrect68 is added to bring the pH of the biodiesel back to 6.8-7.5
To avoid over dosing of the product we recommend the biodiesel is continually mixed while the PHCorrect68 is being added. It is good practice to add the product in stages in order not to over use.
Once the pH has fallen to 6.8-7.5 further mix for 5-10 minutes before adding the filter aid and then carrying on the filtration and polishing processes. |
