Draco Wastewater Sludge Slaying Service via Thermal Hydrolysis Process
Shrink sludge volumes and boost biogas production in your wastewater treatment operation with the powerful and energy-efficient service of thermal hydrolysis.
Reduce sludge volumes by 85% while minimizing energy, disposal, and operating costs
Draco’s patented multi-steam spargers and agitator provide more even heat distribution and transfer, allowing for increased efficiency and energy savings regardless of whether or not your facility has anaerobic digestors.
Central agitator boosts heat transfer and helps maintain a homogeneous state within the reactor.
Patented spargers and agitators allow feeding of concentrated sludge up to 22% dry solids.
Steam is used to build heat and pressure in the reactor vessel, causing cell lysis and improving the dewaterability of cellular sludges.
Even distribution of heat energy within the reactor allows for processing of more concentrated sludges and eliminates unnecessary dilution.
The Draco Service Advantage
Improve Dewaterability
Draco uses only temperature and pressure to breakdown cell walls, releasing trapped water for improved dewatering.
Reduce Takeoff Costs
Draco reduces sludge volumes by a minimum 70% after dewatering and up to 85% after drying, resulting in lower offtake and transportation service costs, reduced tipping fees, and increased sustainability.
Increase Biogas Production
For plants with anaerobic digesters, pretreating sludge feed with Draco service will increase biogas production.
