Durco Enviro-Dri Sludge Dryers By Ascension
The Enviro-Dri Sludge Dryer is ideal for any company that is currently generating hazardous waste that must be disposed of in a hazardous landfill - Waste disposal costs reduced up to 75%
Sludge Dryer Applications
|
Durco Enviro-Dri Sludge Dryers are designed for supplemental dewatering of sludge cake
(>25 wt% solids) up to 90%, greatly reducing waste volume and weight.
The Enviro-Dri Sludge Dryer is typically used in conjunction with a filter press where the filter press discharges its cake directly into the dryer. This integrated design provides a small footprint.
Low-pressure steam (25 psi) contained in a steam jacket provides heating energy while the sludge cake is mixed within the dryer.
Manual or hydraulic operation is available for inlet and outlet doors.
The Durco Enviro-Dri Sludge Dryer is designed for heavy-duty, every day batch waste disposal.
Specific Process Applications Include:
Metal Hydroxides
Inorganic sludge cakes
Organic sludge cakes

Durco Enviro-Dri Sludge Dryer Features & Benefits
Closed Drying Process - Continuous, homogeneous drying reduces volume, controls emissions, minimizes dusting and eliminates leaks or spills.
Quicker Drying Cycle - Quicker drying cycles allow smaller models to handle larger press loads by using inexpensive hoppers.
Indirect Heating - Low temperature heat transfer eliminates incineration and volatile problems. Single operation. All stages take place in the dryer.
Low Pressure Steam Operation - Provides efficient heat source with uniform controlled temperature. Does not require boiler operator.
ASME Code Jacket - ASME Code Stamped trough jacket provides efficient heat transfer service.
Heavy-Duty Drive Assembly - Double helix, heavy-duty rotor and drive assembly. Includes adjustable and replaceable wiper blades.
Dryer Sized To Filter Press - No intermediate material handling. Batch drying operation is independent from press operation.
Sliding or Pneumatic Lift Hatch - Easy access to dryer rotor.
Control Timer - Permits adjustable drying time.
Modular Design - Easy to retrofit in place.
