Total suspended solids (TSS) monitoring provides a practical way to track changes in suspended material in water. For wastewater treatment<\/a>, industrial processes, surface water<\/a>, and other applications, continuous TSS data can help operators identify changes, evaluate treatment performance, and support process and discharge control. Online TSS sensors<\/a> make this information available without relying entirely on laboratory testing.<\/p>\n

Why Is TSS Monitoring Important?<\/strong><\/h2>\n

The importance of TSS monitoring comes from what changes in suspended solids can reveal about a water system. A rising or fluctuating TSS value may be associated with changes in flow, erosion, solids separation, treatment performance, or wastewater conditions. Continuous monitoring helps operators see these changes as they occur rather than only after a sample has been collected and analyzed.<\/p>\n

How Do TSS Sensors Support Water Quality Monitoring?<\/strong><\/h2>\n

Online TSS sensors use optical measurements to estimate suspended-solids concentration. The sensor detects the interaction between light and particles in the water, and the resulting signal is converted into a TSS value through a calibration relationship.<\/p>\n

Unlike the gravimetric laboratory method, which filters a sample, dries the retained residue, and determines its mass, an online optical sensor can provide continuous measurements. U.S. EPA Method 160.2<\/a> describes the gravimetric determination of non-filterable residue\/TSS and reports results in mg\/L. The method applies to drinking, surface, saline, domestic, and industrial waters.<\/p>\n

Application-Specific Calibration Matters<\/strong><\/h2>\n

An optical TSS sensor does not directly weigh suspended solids. Its response depends on the optical characteristics of the particles in the application. Particle size, composition, shape, and concentration can affect the relationship between the optical signal and TSS. For this reason, the sensor should be calibrated or verified against representative samples from the actual process when application accuracy is important.<\/p>\n

TSS vs. Turbidity: What Is the Difference?<\/strong><\/h2>\n

TSS and turbidity<\/a> are related but should not be treated as the same measurement. TSS is a concentration of suspended material reported in mass units such as mg\/L, while turbidity is an optical measurement of the scattering or attenuation of light. A relationship between the two can vary with the characteristics of the particles and the water being measured.<\/p>\n
