Biosolids granulator for waste treatment
Waste management facilities often face challenges in safely and sustainably processing biosolids. The need for effective pathogen reduction, dry output, and flexibility of heat sources makes traditional methods inefficient and limited in application.
Granulates biosolids with minimized pathogen regrowth
The GEA biosolids Granulator is an advanced solution designed to address critical biosolids treatment challenges. This system utilizes a unique process where dewatered particles are immediately heat seared directly from the centrifuge bowl. These particles are further dried using a secondary hot airflow, resulting in granulated material with up to 50% dry solids. The system can use low-grade waste heat available on-site (75–90°C) or heat from an additional fuel source. By minimizing pathogen regrowth and enhancing drying performance, the granulator allows for end-products that are stackable, resistant to weather degradation, and incineration friendly. It is particularly suitable for environmental and agricultural applications, including field storage, composting, and as a fuel additive.
