The amount of dissolved oxygen (DO) in wastewater treatment plants is crucial in maintaining an efficient treatment process. One of the factors that affect DO levels is temperature. As temperature increases, DO levels decrease due to the decreased solubility of oxygen in water. Another factor is organic matter, which requires oxygen to decompose. If there is too much organic matter, it can deplete DO levels to a point where the treatment process is compromised. The presence of certain chemicals and compounds, such as ammonia and sulfides, can also affect DO levels negatively. Maintaining proper DO levels is crucial in ensuring effective wastewater treatment.
