Heliantis™ Solar Sludge Drying
Heliantis™ solar sludge drying processes dewatered sludge into a dry and granulated product for agricultural reuse or thermal energy production and is capable of yielding up to 85% dry solids content.
Heliantis™ Technology
Heliantis™ transforms any type of dewatered sludge (15% minimum dry content) into a dry, granulated product with a dry-solids content that can be adjusted within a range of 35% to 85%. Using the sun as the main energy source, the sludge is dried in a greenhouse and a scarifiying machine turns over and breaks up the sludge into carbon-neutral and odorless granules, for eventual agricultural reuse or thermal energy production using co-incineration.
HOW IT WORKS
- Dewatered sludge is brought directly to the greenhouse as it is produced;
- The rotary scarifier repeatedly turns the sludge, breaking it into granules and gradually moving it forward to the exit;
- As the sludge bed is heated by the sun, the water it contains evaporates;
- The moist air is evacuated to maintain optimum moisture levels in the greenhouse
