heat. lots of it. bubble at 60*C for four hours. dessicant is required if environmental humidity is high.

a carbide manometer is highly recommended.

What I do most, first is to dry biodiesel don't put water in it. I dry wash, but I only make test batch quantities. It is something to consider.

Heat, but NOT "lots of it". Gentle heat, 100-120°F max. Don't promote oxidation of the BD, only a small amount of heat is needed to make the water evaporate out better.
Bubble dry air from a compressor through a desiccant into the bottom of the heated tank.
Blow or suck warm room air across the top of the tank and vent outside. This 'tank air' will contain methanol vapors, so vent accordingly away from sparks, flames or people.
A 250 gallon fuel oil tank makes a good drying tank; a 100CFM 'bathroom fan' with a brush-less induction motor works for an extraction fan.

A carbide manometer is the only low-cost reliable method to measure water in fuel. It's better than the more expensive SandyBrae. http://www.burnveg.com/forum/about72.html
