Innovative Overflow Systems for Zero-Energy Digestate Transfer
Iona Biogas has designed an innovative overflow system connecting digesters to the
digestate pit, operating entirely on the “Unified Vessel” principle with zero energy use. By
leveraging gravity, it cuts pumping energy by up to 66%, reduces equipment size, minimizes mechanical stress, and ensures smooth, continuous material flow.
Smart engineering combined with field experience delivers a sustainable, low-maintenance, and cost-effective solution for digestate transfer—optimizing plant efficiency while lowering operational costs.
