Hazardous Waste Sludge Dryers
The use of an HEI sludge dryer provides up to a 4 to 1 reduction of sludge volume. This results in a dramatic reduction of sludge disposal and handling costs and provides a rapid payback period. HEI manufactures batch process. The batch process dryers use steam, gas, or electric heat sources.

Sludge Volume Reduction
The use of a HEI sludge dryer provides up to a 4 to 1 reduction of sludge volume. This results in a dramatic reduction of sludge disposal and handling costs and provides a rapid payback period. HEI manufactures batch process. The batch process dryers use steam.
The HEI batch dehydration system is designed to meet the stringent environmental requirements for thermal extraction equipment. The design flexibility of the HEI batch dehydrator allows the system to be positioned directly beneath the filtration equipment whenever possible to save material handling. In cases where wet or dried material must be transported, HEI offers a complete line of material handling equipment.
The dehydration process is accomplished by externally heating the dehydration chamber with steam and carefully controlling the internal dehydration temperatures and the dehydration steam exhaust.
Additionally, many wastes can be batch treated that are environmentally objectionable in a continuous dehydration system.
General operation of the HEI batch dehydration system consists of dropping a controlled amount of material through the dehydration chamber door. The process timer is set to the required dehydration time. A custom fabricated steel blender ribbon continuously turns the material exposing all surfaces for dehydration.
When the preset dehydration time (typical cycle is 5 to 6 hours) has elapsed, the unit automatically shuts down. At this time, the operator switches to the discharge cycle to allow automatic emptying of the machine.
HEI batch process dryers come in various configurations and range in capacity from 4 cu. ft. to 60 cu. ft.
