TSS Analyzer and Control System

The Universal Controller model ETX, together with the Triton TR80 and TR82 TSS Sensors (Total Suspended Solids) employ a Nephelometric turbidity sensor designed for use in water and wastewater applications. Turbidity which is the cloudiness or haziness of a water sample, is caused by particles suspended in the water, typically clay and silt. Since bacteria and viruses can be attached to these particles, turbidity has become a critical indicator of overall water quality.

The TSS Analyzer does a calculation of the NTU (Nephelometric Turbidity Units) and provides a TSS readout in percentage. The displayed variable can also be changed to show NTU, PPM, mg/L, or FNU units.

The TSS Sensors TR80 (with wiper blade) and TR82 (no wiper blade) use an optical method for determining the turbidity, a light beam is directed into the sample where it is scattered by suspended particles in the water. The amount of scattering depends on the amount of material in the water, the wavelength of light used, and the size and composition of the suspended particles.

Three detectors monitor the light beam at an angle of 90°. The first detector inside the sensor is the reference detector that compensates for changes in the LED light source caused, which is caused by aging or other variations. The second detector measures a short path length, which is best for high concentration measurements, % concentration and g/L. The third detector measures the longer path length which is best for lower concentrations, FNU and ppm. The turbidity signal is constantly adjusted versus the reference detector and digital filter functions help to suppress interfering signals, while the self-monitoring diagnostics assure a highly reliable measurement.

TSS Analyzer

Description

The Triton TR80 and TR82 TSS sensors use a long-life near-infrared LED light source (880 nm) and the 90° scattered light method in accordance with ISO 7027 / EN 27027, to assure accurate turbidity values under standardized and comparable conditions. The 90° scattered light detection method is the most common sensor design for turbidity. This sensor has the advantage of a high sensitivity at low levels of turbidity, a simple optical configuration and a balanced sensitivity to all particle sizes.
