How much energy does each sludge dryer use per ton of water removed?

ELODE 3000 uses 200–250 kWh, the EVD 3000 uses 300–400 kWh, and a Typical Dryer needs about 1,200 kWh (heat equivalent) because it has to boil the water off.

How much floor space does each dryer need?

The ELODE 3000 is 11 × 15 ft, the EVD 3000 is 15 × 7.5 ft, and a typical dryer is about 80 × 12 ft.

How fast is each dryer?

ELODE takes 3 minutes with a 2-minute startup, the EVD takes 1–2 hours with a 30-minute startup, and a typical dryer takes hours with a startup measured in hours.

Sludge dryer comparison:
ELODE vs. EVD vs. Conventional

Same job — get the water out of your cake. Three very different energy bills, footprints, accessories, and timelines to weigh before you pick a sludge dryer.

ELODE · Electro-osmosis
EVD · Heat pump
Typical Dryer · Boiling

Energy required to remove 1 ton of water

ELODE 3000 · Electro-osmosis dehydration 200–250 kWh
EVD 3000 · Heat-pump evaporation 300–400 kWh
Typical Dryer · Boiling 1,200 kWh (heat equivalent)

ELODE and EVD ship as stock units with minor assembly; conventional dryers are custom builds that need several supporting systems. EVD figures are for the EVD 3000 base unit; an EVD 18000 (~19.8 wet tons/day) is about 64 × 7.5 ft.

Better together

Great alone. More efficient as a pair.

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+
