We have extensive experience in the design, construction, and operation and maintenance of Thermal Drying.

Thermal sludge drying is a treatment process for dehydrated sludge from sewage treatment plants. The objective of this process is to evaporate as much water as possible from the sludge in the safest, most energy-efficient way from both free water and capillary water, obtaining high percentages of dryness depending on the drying process. Thermal drying therefore seeks to reduce and deactivate the volume of sludge generated at the treatment plants.

Our notable projects include the largest Thermal Sludge Drying plant in Europe (Sur, Madrid 300,000 T/year) as a concession.
