Biosolids granulator for waste treatment
Transform raw sludge into valuable granules with a solution that securely dries and granulates biosolids, minimizing pathogen regrowth while efficiently utilizing waste heat for energy conservation.
Granulates and Dries Biosolids Efficiently
The GEA Biosolids Granulator is engineered to transform dewatered municipal and industrial sludge into valuable granulated end-products. By employing a unique multi-stage drying and granulation process, it ensures pathogen reduction and produces granules suitable for agricultural and industrial applications, including fertilizer and fuel additives. This system integrates efficiently into existing processing lines and features a continuous, automated operation that is ideal for large-scale treatment facilities. The granulator makes use of waste heat or fuel sources for energy-efficient operation while maintaining consistent output quality. Constructed with durable materials for enhanced longevity and low maintenance, the equipment supports sustainable recycling pathways and reduces environmental impact.
