  • Hey girlguidebiscuit,

    What I wanted to show was how fast the electrostatic field separated the glycerol from fresh mixed bioD in two different volumes. It works just as well with reacted fresh oil or WVO and is also very very effective at water separation after you wash your biodiesel.

  • Where can I purchase a electrostatic generator in the U.S.??Rac Shac has no idea.

  • Hey derf62172,

    Any high voltage low current transformer will do (6-8kV AC or DC 20mA). I used one from an burner ignition coil.

    NOTE: DON'T GO OVER 20mA current!!! and keep your electrodes submerged so no short circuit occurs (No spark).

  • Hey Northerbrewer,

    No this is pre-mixed VO and Methox

    Rob.

  • Dear Sir,

    If I use 11KV (I have this transformer) 20mA into WVO (direct from the restaurant) it will separate glycerol and it will be safe to use it into my car? I will need to mixe and methanol also?

  • Dear Sir.

    Can I use a welding machine and two pieces of long screw as electrodes separated with a pvc pipe so they don’t touch?

  • Hello Mr. I would like to receive better information with details about their experience, what voltage and what equipment you used for general voltage, details. You used pure oil or WVO, you added caustic soda or the oil was pure, enlighten me please My email: americocandido@gamil.com Att Americo Brazil

  • I've never heard of electricity performing mechanical separation. How does it work? I can't help but think there are other applications for this technique beyond glycerol.

  • could one use a 12v bat and car ignition coil for this operation?

  • @Agrisonic so will it separate glycerol from fresh oil or WVO without adding in the methanol and lye? or does this simply aid the process?

  • I dumped a 240 volt lead with screws attached in my biodiesel and I separated very quickly. Just don't touch the screws!

  • @worldismine69 Usually a high voltage transformer.

  • i believe you can my friend:)
