This study successfully gathered preliminary data and developed a real-time (COD) determination method using UV-visible spectrophotometry. This method is intended to be part of a new product by Valmet that can measure multiple parameters in wastewater. Six samples from four different locations within the Taskila wastewater treatment plant were analyzed, and the data served as a foundation for creating prediction models using MATLAB. The study confirmed the potential of UV-Vis spectrophotometry as a reliable and accurate tool for COD determination in wastewater treatment. However, the MATLAB prediction models would benefit from refinement and validation with larger datasets. This research paves the way for future studies aiming to improve real-time monitoring methods in wastewater treatment for optimal environmental sustainability.
