MSA Scrubber Monitoring System

Many wastewater treatment plants have air scrubber systems to help control odours from hydrogen sulfide emissions. MSA offers both in-situ sensors for large diameter pipes and pre-engineered sample draw systems for those applications that require higher detection ranges up to 500 ppm. Both products can also be used in chlorine scrubber applications with a range of 0-25 ppm.

The MSA Scrubber Monitoring System is a pre-engineered system that is compatible with most wet or dry scrubbers. The system operates within a closed loop so that no gas vents to the atmosphere. Built to withstand harsh outdoor environments, the unit is housed in a heated NEMA 4X enclosure.

Maintenance and calibration are simple procedures. If an obstruction occurs in the sample line, the unit provides flow failure indication. Calibration can be performed with an IR calibrator, eliminating the need to open the system’s front door.

The system ensures the user’s scrubber functions and meets EPA requirements. It indicates breakthrough for carbon bed scrubbers and controls chemical feeds for wet scrubbers. It also conserves expensive chemicals.
