First, after the reaction has completed, let the mixture cool and settle in the tank for a day or two, then drain the glycerin from the bottom.

Second, add water and circulate to dissolve the remaining glycerin and methanol. Let settle and drain. Repeat until water remains clear and the biodiesel turns semi-transparent amber instead of brown.

Dry the product (important) by bubbling air (aquarium air pump used) into the bottom of the drum for several days until the bio is totally clear.

I never did get the result analysed so don't know if any specs were met but the stuff worked well (with the exception of the injection pump seals, which would have happened anyhow even with 100% pure, 100% biodiesel).

BTW, I used an electric hot water heater (with the anode removed) for the reaction vessel -,cheap but worked well. The glycerin also made a great driveway weed killer!
