As has been described,  wvo becomes rancid after a short time in storage at
room temperature.  This deterioration prevents it from being stockpiled for
long periods.  The deterioration,  I presume, is the result of bacteria
buildup with time.

 In water treatment, a uv lamp can be used effectively to remove coliform
bacteria, by placing the uv lamp in the line through which the water is drawn
for use.  Why couldn't  bacteria in wvo be removed by similar uf treatment? 
This could be done continuously, or semi continuously, by pumping a  small
stream of wvo  from the tank, drawing it from the tank bottom with a small
submersible pump and allowing the uv treated wvo to drop back into the top of
the tank.  Assume a 1000 gal tank.

Alternatively, the wvo stream could be heated  and returned to the tank.  Any
idea of what temperature and for how long the residence time through the
heater?  Or would both heating and uv treatment be required?  Comments?
