After pre-dewatering, your sludge still contains between 60 and 75 percent water. Most of the disposal costs are therefore simply spent on water. By using our Drymex® sludge dryers based on heat pumps, you can reduce the weight and volume of your sludge by up to 70 percent. This also means a reduction in your disposal costs by up to 75 percent. You can carry out these types – also known as mobile sludge drying – with our systems:

And there is even more potential in sludge drying.
The drying process may reclassify your sludge, saving you even more money. Depending on the sludge, recycling could also become an option. If individual raw materials could be recycled, you would even have an additional source of income.
All of this would be worth discussing, calculating, and checking. What do you think?
Further details about sludge drying, its functionality, and our standard dryers as well as special systems can be found here below.

Drying systems for industrial sludge
Compact models and special systems
Our Drymex® drying systems are suitable for pre-dewatered, water-containing sludges and substrates. We implement the drying process as a compact version or as a special design. The ideal type of system for you depends on several factors: the type of pre-dewatering, the amount of sludge produced, and your space conditions.
The Drymex® heat pump module of our sludge dryers provides the necessary process air and is also responsible for the condensation process. We work with extremely dry and thus unsaturated air, guiding it homogeneously through the sludge. This combination of efficient air preparation and appropriate air guidance ensures a high-quality drying result.
