Biosolids decanter for municipal sludge treatment
Optimize your sludge processing by maximizing dewatering efficiency and reducing operational costs with advanced centrifugal technology, ideal for continuous high-speed operations in wastewater and environmental management.

Dewaters and Thickens Municipal and Sewage Sludge
The GEA biosolids Decanter is a high-speed centrifuge designed by GEA, tailored for the continuous dewatering and thickening of municipal and sewage sludge. It operates using a horizontal solid-wall bowl framework that excels at separating solids from liquids efficiently, integral to wastewater treatment and environmental management. Capable of reducing sludge volume significantly, it supports a sustainable production environment by lowering transportation and disposal costs. The deep pond design maximizes separation efficiency while the gentle feed geometry promotes optimum flocculation with minimal wear. Constructed from stainless steel, the decanter ensures durability and corrosion resistance. Highly energy-efficient, the GEA biosolids Decanter employs the GEA summationdrive® for automatic torque measurement and differential speed control, complemented by optional GEA varipond® technology for maintaining consistent solids concentration amidst variable feed conditions. Its modular design allows for easy configuration, enabling seamless plug-and-play integration into existing systems. Maintenance is simplified with easy access to components, ensuring minimal downtime. The GEA biosolids Decanter reduces energy consumption by up to 60% in the pro series, validated by the Add Better label from TÜV Rheinland. With configurations suitable for diverse industrial needs and customizable options, it addresses specific operational challenges in sludge processing while optimizing resource recovery and environmental impact.
