The issue with conventional methods for wastewater treatment is their high space usage and energy consumption, which result in elevated operational and installation costs. Granular Biomass offers a more efficient solution. Its continuous method uses granular biomass in a three-phase process: first, wastewater is mixed in an aerobic reactor with granular biomass; next, the treated water moves to a second similar aerobic reactor; and finally, the water flows to a decanter, where the treated water is separated through a supernatant. This method reduces the required space by 75%, energy consumption by 30-48%, and investment costs by 50% compared to current methods.
The invention enables the generation of aerobic granular biomass in continuous-flow systems that replicate the substrate concentration and hydrodynamic conditions of sequential batch reactors. This system achieves volumetric removal rates of up to 4 kg COD/m³·d, significantly outperforming conventional activated sludge systems, which treat loads of approximately 1 kg COD/m³·d, with equal or better effluent quality.
