GEA biosolids Granulator
Innovative dry-on-demand solution for biosolids treatment
Stackable end product with minimized pathogen regrowth
The unique process utilizes small dewatered particles – ejecting directly from the rotating centrifuge bowl – which are then immediately heat seared and fixed by the primary direct heat injection stream. These solids are then further dried by the secondary hot airflow in the main drying chamber. This results in an enhanced dried granulated material with up to 50% dry solids with a sustained pathogen count below 100,000 cfu/g.
It’s possible to achieve these process results using either low-grade waste heat available at the site (75–90°C), heat generated from a fuel source, or a combination of both.
