Dry sludge without heat
“We are saving so much money with this machine.”
— Bart Boles, General Manager
“It really does reduce our solids by 60% in 3 minutes.
This technology could be a game-changer for our industry.”
— Josh Thompson, Superintendent
“We’re glad we bought the ELODE machine.
It is even more valuable because it gives us goodwill with the Daviess County landfill. They love our sludge.
It is a slam dunk decision.”
— Kevin Roberts, Director of Operations

How ELODE dries sludge without heat
The Electro Osmosis Dehydrator (ELODE, pronounced E-Load) further dewaters cake produced by mechanical dewatering equipment (eg. belt press, screw press, centrifuge).
ELODE typically reduces cake weight by 50% or more in just 3 minutes. It consumes 300 kWh to remove 1 ton of water, using only electricity - no heat, chemicals, or mechanical force.
Rather than using heat to boil water to steam like conventional thermal dryers, ELODE uses electrical polarity differences between solids and water to “shock” the water out of the cake via electro-osmosis. Our proprietary process has over 8 patents.
