WasteWater Management and Treatment Plants


Sewage odor is often the number one complaint attributed with wastewater treatment and waterworks facilities. The sewage odor is mainly due to hydrogen sulfide gas. The use of Chemteq filter’s replacement indicator on the outlet of filter or carbon absorber alerts the user when filter or carbon absorber is saturated and exhausted. Our filter replacement indicators, not only ensures the health and well-being of the wastewater treatment staff, but also ensures that residents in the vicinity of the plant are breathing odor-free air.

Facts about hydrogen sulfide

Hydrogen sulfide is an extremely hazardous gas which can be immediately life threatening at high concentrations (300 mg/m3 or 200 ppm)1. As concentrations approach 100 ppm, odor becomes imperceptible because of olfactory (sense of smell) fatigue. At these levels, the gas disrupts cellular respiration and may cause profound respiratory depression as well as cardiac dysrhythmias. At a concentration of 150 ppm, the olfactory nerve is paralyzed2. Hydrogen sulfide causes Inflammation of the moist membranes of eye and respiratory tract, olfactory neuron loss and death3.
