Aerobic Granular Sludge (AGS) is a wastewater treatment technology that uses dense, granule-like aggregates of microorganisms to remove pollutants. Unlike traditional activated sludge systems, AGS settles quickly, allowing for more efficient separation of treated water and sludge. This process enhances the treatment efficiency and reduces the footprint of treatment facilities. The granules in AGS are formed under specific conditions that promote the growth of certain bacteria, which are effective in breaking down organic matter. This method not only improves the quality of treated water but also minimizes energy consumption and operational costs associated with wastewater treatment, making it an attractive option for municipalities and industries.
