Mr. Cardoso, It is presumed that the "water-methanol mix" that you are referring to is the microscopic residue after the washing stages are completed, as there is no water in the biodiesel prior to washing.
If that's the case, you'll find that there is no need to elevate the temp much above 120*F in order to get the the microscopic water droplets to coalesce and fall out. Going beyond the 120* range and trying to distill the water out would generate a needless expenditure of fuel and the high heat - somewhere in the realm of 230* F - would begin to degrade the fuel unnecessarily.
