SOLITAX sc turbidity / suspended solids analyzer

Principle of Operation

• Inside the measurement probe of the SOLITAX™ sc online suspended solids monitor, a built-in LED light source is positioned at a 45° angle and emits 880 nm near-infrared light into the sample. After the beam is scattered by suspended particles in the sample, scattered light at a 90° angle to the incident light is formed, detected by the detector in that direction, and calculated to obtain the turbidity of the sample. When measuring sludge concentration, scattered light at a 140° angle to the incident light is formed and detected by the rear detector in that direction. The suspended solids monitor then calculates the signal intensities detected by the front and rear detectors to provide the sludge concentration value.

• Because the LED emits 880 nm near-infrared light, the inherent color of the sample does not affect the measurement result of the suspended solids monitor.

Typical Applications

The SOLITAX™ sc online suspended solids monitor can be used in wastewater treatment plants to measure sludge concentration and evaluate activated sludge quality or the entire biological treatment process; in waterworks for turbidity measurement of filter backwash water, raw water, and sedimentation tank effluent; and for monitoring water quality in industrial production processes / circulating cooling water.

Instrument Features

• The SOLITAX™ sc online suspended solids monitor uses dual-beam infrared and scattered-light photometer detection technology.

• The SOLITAX™ sc turbidity/suspended solids detector can measure both turbidity and suspended solids (or sludge) concentration.

• The SOLITAX™ sc online suspended solids monitor uses an 880 nm near-infrared LED light source and can compensate for sample color.

• The SOLITAX™ sc online suspended solids monitor offers multiple measuring ranges, sensor materials, and installation methods to meet various application requirements.

• The SOLITAX™ sc online suspended solids monitor enables continuous measurement with fast response, suitable for continuous monitoring and control

• The SOLITAX™ sc turbidity/suspended solids detector features a self-cleaning system, stable operation, and low maintenance
