QUESTION: How do I better control odor?

ANSWER: Tired of community complaints about the rotten egg smell coming from your facility? Sulfur reducing bacteria (SRB) naturally occur as the result of organic material decay and can easily convert sulfates to hydrogen sulfide – the malodorous gas that emits from raw water wells and wastewater treatment collection systems and plants.

Magnesium hydroxide (Mg(OH)2) naturally inhibits the development of hydrogen sulfide odors in two key ways. First, by boosting liquid pH levels, which takes SRBs out of their ideal metabolic range and keeps any dissolved hydrogen sulfide gas in solution and out of the atmosphere.

Second, solid Mg(OH)2 particles absorb the dissolved sulfides and other odor causing compounds. This process additionally neutralizes the acidic conditions where odors and corrosion occur.
