Which parameters are typically monitored in a wastewater treatment facility?

The selection of BOD (Biochemical Oxygen Demand), TSS (Total Suspended Solids), pH, nitrates, and phosphates as the monitored parameters in a wastewater treatment facility is grounded in the need to assess the effectiveness of the treatment process and to ensure that discharged effluent meets regulatory standards.

BOD is a critical parameter because it measures the amount of oxygen that microorganisms will consume while decomposing organic matter in the water. A high BOD indicates a high level of organic pollution, which affects the aquatic ecosystem when effluent is discharged. Total Suspended Solids (TSS) is significant as it represents the solids that are suspended in the wastewater, which can contribute to sedimentation issues in receiving waters, and can also harbor pathogens and pollutants.

pH is essential to monitor because it affects the solubility and toxicity of chemical constituents in the wastewater. Maintaining a balanced pH is crucial for the health of microbial populations involved in the treatment process. Nitrates and phosphates are key nutrients that can lead to eutrophication in surface waters if they are present in high concentrations in treated effluent. Monitoring these parameters is essential to manage nutrient loading and protect water quality downstream.
