The dehumidification modules are closed systems in which warm humid air is recirculated and reused within the drying module. No heat emissions and no odor are generated during the treatment process. The final product (Dried Biosolids) meets the Vector Attraction Reduction (VAR) as per U.S. EPA 503 Rule.
The power requirement is very small compared with other sludge drying systems. Different types of power systems can be used depending on the objectives of the project. Electric power is usually used as the power source. Solar, solar thermal, combined heat power (CHP) including waste heat and other potential power sources can be used to power the system.
The final product is certified Class A Biosolids meeting vector attraction reductions as per U.S. EPA 503 rule requirements. It can be used for agricultural production as a fertilizer, soil amendment, filling materials for civil engineering projects, capping materials for capping closing landfills, gasification to generate syngas, gasification to generate electric power, and other multiple beneficial reuses.
