Advantages and Comparison
Our low temperature batch and continuous drying system is designed to dry sludge produced by either a plate and frame filter press, a belt filter press, a centrifuge or some similar dewatering device. The sludge cake is dried by the injection of recycled, warm, dry air. The saturated air which comes off the top of the sludge container is passed over refrigerated coils, where the moisture is removed, and then reheated prior to injection into the container. That closed loop drying process eliminates emissions to the air and the burden of DOE air permits.
We furnish extremely dry, unsaturated air and pass it uniformly through the sludge. Efficient air conditioning combined with adequate air routing ensures quality drying results.
1. Dehumidification module / drying container interface – Humid air is extracted from the drying chamber and passed to the dehumidification module.
2. Moisture precipitates on the air cooler fins, and the condensate water leaves the system through the condensate collector and the condensate drain.
3. The air heater raises the air temperature to the level required for the process.
4. The process air fan provides the required air circulation between the dehumidify cation module and the drying chamber.
5. The dried, unsaturated air is now returned to the drying chamber.
Our sludge drying technology will reduce the weight and volume of your sludge by as much as 60-75%. Therefore disposal cost will also reduced by 60-75% less.
