A typical municipal wastewater treatment facility processes millions of liters of wastewater each day and utilizes numerous pumping stations, sludge digesters, and chemical treatment units. Hydrogen sulfide gas is produced during the decomposition of organic matter in wastewater systems and can accumulate in confined spaces such as sewer tunnels and sludge tanks. 

Semiconductors: Semiconductor manufacturing facilities require extremely precise gas detection systems due to the use of highly toxic and reactive gases during chip fabrication processes. Gases such as silane, phosphine, arsine, and hydrogen are commonly used in semiconductor production and must be carefully monitored to prevent hazardous leaks.
