Hydrogen Sulfide treatment- H2S Gas in Wastewater - Aquafix
The sulfide ion, S , does not exist in aqueous alkaline solutions of Na2S. Instead sulfide converts to hydrosulfide: S + H2O → SH + OH Upon treatment with an acid, sulfide salts convert to hydrogen sulfide: S + H → SH SH + H → H2S Webhydrogen sulfide can be formed whenever elemental sulfur or sulfur-containing compounds come into contact with organic materials at high temperatures. Hydrogen sulfide is … how do i make my facebook page private

Effect of initial sludge pH on H 2 S formation during batch mesophilic anaerobic digestion of slaughterhouse wastewater sludge was studied in this paper. The results demonstrated … Hydrogen sulfide is most commonly obtained by its separation from sour gas, which is natural gas with a high content of H 2S. It can also be produced by treating hydrogen with molten elemental sulfur at about 450 °C. Hydrocarbons can serve as a source of hydrogen in this process. Sulfate-reducing (resp. … Meer weergeven Hydrogen sulfide is a chemical compound with the formula H 2S.
