Yes yes yes...this is correct...question how much water are you trying to
treat and how quickly...I have a home system that does exactly this and it

Subject: [biofuel] stockpiling wvo
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?
