Sludge/Biosolids Dryer
Efficiently dries sludge into stable products, lowers disposal expenses, and transforms waste into valuable resources.
Our advanced sludge dryer features dual counter-rotating shafts with specially designed intermeshing wedge-shaped paddles, ensuring uniform heating and exceptional heat transfer efficiency. Utilizing hollow paddles for enhanced heat transfer, our compact machine operates with high thermal efficiency of approximately 98%. Indirect heating with steam or circulated thermal fluid (hot oil) minimizes the need for additional treatment, while producing minimal non-condensable gas, effectively reducing odor issues. Experience the superior performance and reliability of our sludge dryer, engineered to provide cost-effective and environmentally friendly sludge management solutions.

System and Design
At JXX Drying, we offer a reliable and efficient solution for sludge drying with our advanced sludge dryer technology. Using indirect heating methods such as steam or thermal fluid, our sludge dryers achieve high energy efficiency and produce minimal off-gas, making them an environmentally friendly and cost-effective choice for wastewater treatment. The system is designed to handle a wide range of feed solids without the need for pre-conditioning, reducing capital and operational costs.
Our sludge dryer features a unique design with dual counter-rotating shafts and intermeshing paddles that optimize heat transfer and ensure thorough mixing. This self-cleaning mechanism enhances heat contact and delivers a compact machine with a high heat transfer area-to-volume ratio. The indirect heat transfer, combined with an insulated dryer, minimizes heat loss and ensures maximum thermal efficiency while occupying less space and lowering installation costs.
Flexibility is key in JXX sludge dryers. They are designed to handle different phases of sludge, from wet to dry, without requiring additional torque during challenging conditions. With no need for external sweep gas, the system produces minimal exhaust gas, keeping odors under control. Our experienced team provides support throughout every phase of the project, ensuring you get a tailored sludge drying solution for your specific needs.

What is a sludge drying system?
A sludge drying system is an efficient process that reduces the moisture content of wastewater sludge, transforming it into a stable, easy-to-handle, and reusable product. This system significantly reduces sludge volume, lowers disposal costs, and enables safe, environmentally friendly waste management, making it an essential solution for wastewater treatment plants and industrial facilities.
What are some common sludge drying methods and sludge dryer machines?
Common sludge drying methods include direct heat drying (rotary drum dryers, belt dryers), indirect heat drying (paddle dryers, hollow-screw dryers), solar drying (greenhouse solar dryers), vacuum drying (vacuum drum dryers), and fluidized bed drying (fluidized bed dryers). Each method is chosen based on sludge characteristics and desired outcomes.
What Dryness Level Can be achieved with a Sludge Dryer?
A sludge dryer can achieve dryness levels ranging from 30% to 99% dry solids, depending on the technology used and the desired application. Intermediate levels (30-50% dry solids) are suitable for composting, while higher levels (70-90% dry solids) are ideal for reducing volume for disposal. For Class A biosolids or energy recovery, the dryer can reach very high dryness levels of 95% or more.
What is the optimal temperature required for a sludge dryer to effectively dry sludge?
The optimal temperature for a sludge dryer typically ranges between 80°C to 120°C (176°F to 248°F), depending on the type of sludge and the drying technology used. Low-temperature dryers often operate around 60°C to 80°C (140°F to 176°F) to preserve valuable nutrients and reduce energy consumption, while high-temperature dryers can go up to 180°C (356°F) for faster drying times. Choosing the right temperature is crucial to maximize energy efficiency, minimize operating costs, and ensure safe and effective sludge drying.
What can dried sludge be used for?
Dried sludge can be used as a soil amendment or fertilizer, composted to enhance soil health, utilized as a renewable energy source, incorporated into building materials, or applied in land reclamation projects, offering sustainable and cost-effective solutions for waste management.
