Innovative dry-on-demand solution for biosolids treatment
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.

Raw sludge from product feed versus granulate from GEA biosolids Granulator
The end product opens additional end-user recycling opportunities, such as agriculture, composting, or incineration as a fuel/fuel additive.
A perfect solution for plants with limited disposal and recycling capacities that want to future-proof their processes in terms of circular economy, sustainability and ecological footprint.


The GEA biosolids Decanter is a continuously operating centrifuge with a horizontal solid-wall bowl designed specifically for (pre)dewatering and thickening of municipal sludge.

GEA sludge Decanters provide an energy-efficient solution for the dewatering of sludge from industrial waste water and water treatment plants.

GEA Intellicant – engineered intelligence to monitor, automate and optimize your sludge dewatering process.
Whether it’s a fad or the future, 100% vial traceability is becoming an increasingly important consideration in the pharmaceutical freeze drying industry. Keeping a close eye on developments is GEA. We’re investigating possible solutions and, what’s more, we have the experience, expertise and know-how to implement them.
There was a time when the phrases ‘non-alcoholic beer’ and ‘tastes good’ were seldom used together in the same sentence, particularly by consumers. But low-proof and alcohol-free beers have come a long way – many of them now refreshing drinks in their own right – thanks in no small part to technology from GEA.
At GEA, our commitment to engineering for a better world fuels our pursuit of innovative solutions that enhance patient care and safety. One of our most promising ventures in recent years is aseptic spray drying – a technology that promises to revolutionize pharmaceutical manufacturing.
