Hydrogen sulfide is frequently found in water with excessive iron and manganese. Crystal Quest® Whole House Iron, Manganese, and Hydrogen Sulfide Water Filters contain naturally mined ore of manganese dioxide, which has been used in water treatment for more than 75 years for hydrogen sulfide, iron, and manganese reduction.
Manganese Greensand is a black, granulated filter media capable of removing or reducing contaminants like iron, hydrogen sulfide, and manganese in drinking water from municipal water supplies and private well. It is an effective filter material used in the United States since the 1950s for the removal of iron, manganese, and hydrogen sulfide in ...
Hydrogen sulfide is used for passivation of the walls of reactors operating at high temperature in petrochemical operations such as steam cracking and hydrodealkylation. ...

Hydrogen sulfide can also result from industrial activities, such as food processing, coke ovens, kraft paper mills, tanneries, and petroleum refineries.Hydrogen sulfide is a flammable, colorless gas with a characteristic odor of rotten eggs. It is commonly known as hydrosulfuric acid, sewer gas, and stink damp.
Manganese greensand is another common treatment method for removing sulfur from drinking water. It is usually recommended for water that contains less than 6.0 mg/l hydrogen sulfide. A manganese greensand filter has a special coating that oxidizes hydrogen sulfide gas to solid sulfur particles, which are filtered.
The hydrogen sulfide removal is mostly due to the air stripping out hydrogen sulfide from the water; the oxygen in air can convert hydrogen sulfide to sulfate, but the reaction is slow. Proper pH control during aeration is necessary to get high percentage removal of the sulfides, with removal efficiency improving with lower pH.
