Sludge Dryers for Wastewater
Reduce weight and produce quality biosolids
Thermal drying equipmetn or solar drying drying technology are one of several methods that can be used to reduce the volume and improve the quality of wastewater biosolids.
Veolia offers several dryers to product safe and hygienic biosolids that are biologically stable which allows for long-term storage as well as a broader range of resource recovery options, either as energy or material.
Sewage Sludge Drying Systems & Solutions
Evaporis* LT belt dryers - based on Veolia’s experience of thermal drying at low temperatures, Evaporis LT Systems Dryers enable the use of low grade waste heat covering up to 100% of the heat demand to fully dry to 90% DS in an intrinsically safe system, easy to operate and lower odor creation potential.

Evaporis* LE - an innovative and patented combination of proven technologies, allowing the advantages of both direct and indirect dryers, with unmatched energy demand performance in a dust free environment. The Evaporis LE allows for a broad range of feed and output product percent dry solids. Read more here.
Heliantis* Solar Dryer – transforms any type of dewatered sludge (15% minimum dry content) into a dry, granulated product with a dry-solids content that can be adjusted from 35% to 75%. Using the sun as the main energy source, the sludge is dried in a greenhouse and a scarifying machine breaks up the sludge into carbon-neutral and odorless granules. Read more here.
