MSA's Odor Scrubber Monitoring System provides valuable real-time H₂S removal efficiency data for optimum control of odors and pollution from waste biogases to wastewater plant operators.

With the increased concern about clean air, many wastewater treatment plants have added scrubber systems and biofilters to control odors and pollution from hydrogen sulfide (H₂S) and other waste biogases. Known for its rotten egg smell, H₂S is a colorless, clear toxic gas that is a potential danger to employees and frequently is the source of obnoxious odor complaints from nearby downwind residents and businesses.

There are a number of benefits derived from H₂S scrubber gas monitoring systems:

• Ensures odor scrubbers meet EPA requirements
• Provides early warning alerts to the potential breakthrough of carbon bed scrubbers
• Helps control chemical feeds for wet scrubbers
• Conserves expensive chemicals
• Helps eliminate odor complaints from the community

Built to withstand harsh outdoor environments and high-moisture samples, the MSA Scrubber Monitoring System is housed in a heated NEMA 4X enclosure and includes an ULTIMA^® X5000 gas monitor, pump, filter, calibration port and 3-way valve.

Maintenance and calibration are simple procedures. If an obstruction occurs in the sample line, the unit provides a flow failure indication. MSA’s Sample Tap Assembly is designed to eliminate high moisture at the pick-up point on vertical stacks. All sample tubing outside of the scrubber should be heat traced to further reduce moisture  development within the system.

The Odor Scrubber Monitoring System is just one example of MSA's safety solutions that are engineered to meet the demands of the water/wastewater industry.
