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.

Sustainable drinking water production in Indonesia
Climate change and a growing world population put increased pressure on the energy-intensive food industry to feed more people without further impacting the planet. George Shepherd, GEA’s Global Technical Sustainability Manager, explains how GEA uses its engineering know-how to help processors produce more sustainably yet increase productivity.
The world's population is growing and with it demand for milk. Dairy is an essential component of many global diets. However, its production can be resource-intensive and impact the environment. GEA’s Christian Müller, Senior Director Sustainability Farm Technologies, sheds light on how technological innovations powered by GEA make milk production more efficient and profitable.
Every safe beverage and bite of food is a victory against invisible microbial threats – a battle shaped by a century of hygienic process design. With more than 100 years of engineering and hygienic design know-how, GEA sets the industry standard for processing equipment that protects food and saves lives.
