The first pour into the dewatering box yielded a total of 7,500 gallons of 2% solids from the aerated digester. The first pour into a 30' x 60' EcoTube™ yielded 30,000 gallons of 2% solids from the aerated digester.
Subsequent pours into the dewatering box have resulted in a total of 14,000 gallons into the box that yet to fully dewater.
In comparison, the 30' x 60' EcoTubes™ have dewatered a total of 300,000 gallons of 2% digester sludge with room for additional sludge! The sludge in the EcoTubes™ when hauled away will yield between 16-25% solids.
