Chemical Scrubbers
Chemical scrubbers are a common odor control technology. Chemical scrubbers can remove up to 99.5% of hydrogen sulfide and ammonia, even at high concentrations.
Usually chemicals such as sodium hypochlorite and sodium hydroxide is used in the solution to oxidize hydrogen sulfide. The oxidation reactions are dependent on pH, with the optimum scrubber solution pH being in the 9.5 – 10.5 range.
