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? Glenn Ellis [Non-text portions of this message have been removed] --- End forwarded message ---
