This study analyzes the performance of a low-cost automated Sequencing Batch Reactor (SBR) developed for small-scale wastewater treatment. An ATmega 328 microcontroller programmed in LabVIEW was used to control reactor operations. Trials with commercial wastewater were conducted for 35 days, evaluating parameters such as chemical oxygen demand (COD), sludge volume index (SVI), solids retention time (SRT) and food-to-microorganism ratio (F/M). Up to 90 % COD removal was achieved with stable process control. The study confirms the viability of this technology for decentralized applications with variable inflow characteristics.
