Transcript Slide 1

Biodiesel with the glycerine layer removed and ready for
washing.
Add about 300-400 ml of water for washing out the
residual soap that is suspended in the biodiesel.
After mixing in the water, slowly agitate the mixture for
about 30 seconds or so and then let settle. Soapy water
will settle out to the bottom the top layer is biodiesel.
During the washing process the
biodiesel will look like orange juice.
When the wash water remains clear after shaking, all soap has been
washed out. This may take 3 or 4 washings. Drain the water and
begin the drying process.
The drying process (removing any remaining droplets of
water suspended) involves bubbling the biodiesel, this will
cause the diesel to become translucent. The higher that
the oil titrates the “darker” the final product will be. It will be
clear but will have an “apple juice color” to it. You can also
set it outside in the sun or on a greenhouse bench to dry.
A reprocess test can be performed
to check for conversion and quality.
