Overview

Therma-Flite has designed the Therma-Flite IC and IB series ‘Bio-Scru’ biosolids dehydration systems with design criteria to address the needs of all small and medium size municipalities or biosolids processors.  Our goal is to keep operator attention and maintenance cost at a minimum, while achieving a consistent Class A material and reducing or removing disposal costs completely.  

For many reasons the disposal of Class B has become a problem that is the concern of any wastewater utility district.  With the limited landfill capacities and the high cost of tipping fees not to mention the high cost of transportation, simply getting the sludge off site is an expensive undertaking.  Then there is the record keeping and liability of the Class B sludge as well as the public relations problem with the disposal of Class B sludge.

Under 40 CFR, part 503 the United States Environmental Protection Agency has published regulations for technologies to further reduce pathogens in Municipal biosolids, to reach Class A, Excellent Quality, biosolids that is safe for the environment.  With the publishing of these regulations Municipalities now have new choices in the safe disposal of biosolids as opposed to the regulations addressing Class B biosolids, the:

Therma-Flite has designed two types of dryers for your Biosolids applications.   Included in each system is a hopper for storage of product, a thermal fluid heater, an air condenser, and integrated controls.

The IC Systems
1800, 3600, or 5400 pounds of water removed per hour

 The IC units are designed to be 'true continuous’ as the wet biosolids are fed from in-feed to the dehydration chamber to the discharge end in a continuous flow.  Automated PLC systems allow for operators to handle other tasks and run the system ‘worry free’.  Our exclusive rotor designs ensure thorough agitation and breakage as well as a consistent discharge of material that is Class A qualified.

 The IB systems
500 or 800 pounds of water removed per hour of operation

 The IB units are designed to be ‘batch’ systems as the wet biosolids are fed into the drying chamber directly.  The system can then be set to dehydrate by an operator who does not need to monitor the unit.  Once the drying process has begun, automated control systems ensure safety, efficiency and minimal operator attention.  After the product is dry, the unit can be discharged right away or used for storage until the product is ready for use.
