Continuous, Automatic early warning systems

Use the Hach® UVAS plus sc UV Absorbance/Transmittance sensor to continuously protect plant treatment processes from high influent organic loads.

Control Activated Sludge Processes

Activated sludge processes require precise balancing of organic load, aeration, and nutrients. Continuous trending of the organics using the UVAS plus sc sensor can help operators know how to balance other factors resulting in cost and time savings.

Suitable for quaternary treatment

The combination of two Hach UVAS plus sc sensors allows continuous monitoring of micropollutants reduction in advanced treatment stages.

Self-cleaning wiper system

The detector windows are automatically cleaned by a built-in wiper that eliminates surface films or particles that can diminish accuracy.

Monitor effciency of UV disinfection process

Hach’s UVAS plus sc is designed to provide continuous UV light transmittance (UVT) measurement of pre-disinfected source water. Operational costs related to sampling for UVT may be reduced with continuous on-line measurement.
