Agitator for biogas digesters in anaerobic digestion
Achieve efficient anaerobic digestion and optimal biogas recovery by maintaining substrate homogeneity and preventing sediment formation, ensuring maximum energy efficiency and continuous operation in your biogas digestion processes.

Ensures Homogeneous Mixing and Temperature Control
The LUMPP Agitator from HASLER Group is designed specifically for biogas digesters and anaerobic digestion processes, providing efficient and continuous mixing to enhance biogas production. This industrial agitator combines large impeller diameters with moderate speeds to ensure high torque without excessive energy consumption. It is equipped with ATEX-certified motors and a robust mechanical seal system to prevent gas leaks, ensuring safe operation in potentially explosive environments. The agitator’s dual-impeller design prevents sedimentation and crust formation, maintaining uniform substrate distribution and consistent temperature throughout the digester. Suitable for wastewater treatment and biomass facilities, it can handle tank volumes from 1,000 to 6,000 m³ and features low-maintenance components for easy servicing. The LUMPP Agitator supports operational efficiency by optimizing digestion time and maximizing biogas recovery, making it an essential component for modern environmental and waste management systems.
