Construction of plywood frame to form "tank". Another view of plywood frame showing

trailer frame suspended by rope.

Tank lined with blankets to protect the

plastic lining that will be put in.

Filling the tank. 1600 gallons later.......

1/2" rebar electrode arrays. Rebar is cut

and stapled to 2x4 runners.

Arrays in place. Note wires connecting

all the electrodes together.

12 hours into the process - Is it soup yet?

After skimming the crud off the top of

the water, this is what is looks like.

36 hours later, it's almost finished! The de-rusted frame loaded up for

transport.


Plywood tank walls are about 30" tall. Supports start 14" down from top. The tank "springs" to help reduce damage from bumps. A DC welder (+) was connected to electrode grid, the (-) connected to the trailer frame. The welder was set to the lowest setting, allowing a 100% duty cycle. (up to 80 volts dc at up to 125 amps) Cleaning process for the trailer frame took about 56 hours total and about 80 feet of rebar. Special thanks to Terry Lingle for the photos. Terry has also cleaned up a metal lathe using electrolysis, proving that this process is limited only by your imagination (and perhaps your wife's patience and your water bill)
