The process, which is unique in the world to date, combines two GEA competencies: centrifuge-based dewatering and drying technology. The end product opens up additional recycling options for the end user, for example in agriculture, composting, or incineration as fuel and fuel additive. GEA has now received the prestigious "Innovative Technology Award" from the Water Environment Federation (WEF) for the GEA biosolids Granulator. Henni Weweler, GEA Senior Director Line Business Environment - Business Unit Separators, and James Hanson, P.E., GEA Mechanical Equipment US, accepted the prestigious award during a ceremony at the WEFTEC 2022 event in New Orleans. The award was presented by Jamie Eichenberger, P.E., past president of the Water Environment Federation.

Stackable end product with minimal pathogen regrowth
GEA experts have developed a technology that is entirely in line with a successful circular economy. The residual energy from the ejection of the dewatered solid from the rotating centrifuge bowl is put to use by allowing the particles to move freely in a drying chamber.

These particles are then immediately heated by a stream of hot air whereby moisture efficiently evaporates. The particles are then further dried by a secondary hot air stream in the drying chamber. Within seconds, the result is an improved dried granule with up to 50 % dry solids. These process results can be achieved using either low-temperature (75 – 90 °C) waste heat available on-site, heat generated from a fuel source, or a combination of both.
