"It really does reduce our solids by 60% in 3 minutes."

Want to test your sludge?

Send a few 5-gallon buckets — we'll run your sludge on a commercial unit in New Jersey, or bring a trailer-mounted unit to you.

Why no heat?

What if you didn't have to boil water when drying sludge?

Thermal dryers don't just heat water — they turn it into steam. That phase change, the latent heat of vaporization, costs more energy than all the heating before it.

ELODE uses electro-osmosis to move water out of the sludge as a liquid — no phase change, no wasted energy.

How ELODE works

ELODE process diagram: sludge cake enters between the anode drum and cathode caterpillar track, water is driven out by electro-osmosis, and drier cake discharges

1

Feed

Dewatered cake spreads evenly across the 3-meter belt.
2

Dry

DC fields pull water out; no heat, instant separation.
3

Discharge

Cake leaves at half the weight or better, and continues to dry as it is conveyed away.

Better together

Need Class A or higher solids? Add the EVD.

ELODE cuts most of the weight for a fraction of the energy. Feeding that drier cake into the EVD means a smaller unit, less runtime, and lower cost per ton to reach 90%DS+.

Press · 15%DS
ELODE · 35–45%DS
EVD · 90%DS+
