Is there an odor?
The dehumidification module is a closed system and warm humid air is recirculated and reused within the drying module. No heat emissions and no odor is generated during the treatment process. At final product (Dried Biosolids) meets the Vector Attraction Reduction (VAR) as per U.S. EPA 503 Rule.
How soon can we get the equipment?
It depends on the size of the project. On average, it takes about 4 months to size, design, build and commission the treatment system from the date of contract signing.
What else will we need before the equipment comes?
Each project is unique from the initial inquiry to the final build. Contact us to discuss your specific needs so that we can create the best combination of products for you.
Do I need a power source? / Can it be solar powered?
Power requirement are very small compared with other sludge drying systems. The answer is yes, the system requires energy to operate. 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.
What happens with the biosolids? Who is responsible for removal?
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 closed landfills, gasification to generate syngas, gasification to generate electric power, and other multiple beneficial reuses that Dr. Akrum Tamimi, a professor at the University of Arizona and his students are researching.
How many of these units are in use in the United States?
One . We determined that a modular demonstration model was necessary for pilot studies.
How dry can it get the sludge?
Typically it is dried to 70-90% solid (30-10% moisture). If dried beyond 90% the product becomes dust.
What are the benefits over traditional de-watering systems?
Dewatering systems usually dewater sludge to 70-80%water and it is still very heavy. This means transferring that weight in sludge and water to the landfill. These units will dewater 30-10% water, thereby delivering a useful bio-solid as a green by-product.
