What is the main purpose of measuring total dissolved solids (TDS) in wastewater treatment?

The main purpose of measuring total dissolved solids (TDS) in wastewater treatment is to understand the concentration of dissolved substances present in the water. TDS includes a variety of constituents such as salts, minerals, and organic matter that are dissolved in water. By assessing TDS levels, operators can gain insights into the overall quality of the wastewater and the effectiveness of treatment processes.

High TDS levels can indicate a concentration of contaminants that may affect the efficiency of treatment systems and the eventual discharge quality. Understanding TDS is crucial for ensuring compliance with regulatory standards, optimizing treatment processes, and protecting the aquatic environment into which the treated wastewater is discharged.

Monitoring TDS provides valuable information that can guide operational decisions, such as adjusting treatment chemicals or processes, to ensure that the final effluent meets required standards for safe discharge or reuse.
