Method of preventing hydrogen sulfide odor generation in an aqueous medium
View Patent ↗The present invention relates to a fast acting chemical treatment for preventing the generation of hydrogen sulfide odor by the microbial metabolic activities of sulfate reducing bacteria. Specifically, the invention relates to a method for preventing hydrogen sulfide odor generation in a sulfur species-containing aqueous medium, which includes adding to the aqueous medium an effective amount for the purpose of a sulfide scavenger treatment selected from the group consisting of glyoxal, triazine, n-chlorosuccinimide, and mixtures thereof.
1. A method for preventing hydrogen sulfide odor generation in a sulfur species-containing aqueous medium, which comprises adding to the aqueous medium an effective amount for the purpose of a sulfide scavenger treatment including a non-biological combination of (a) glyoxal and (b) magnesium nitrate, wherein from about 2-6 ppm of the treatment is added to the aqueous medium, wherein said aqueous medium has a pH of about 6.5-8, and wherein the weight ratio of (a) to (b) is from about 1:3 to 1000:1.
2. The method as recited, in claim 1 , wherein the addition is conducted at a temperature of from about 0° C. to about 50° C.
3. The method as recited in claim 1 , wherein said aqueous medium comprises a wastewater medium.
4. The method as recited in claim 1 , wherein the weight ratio of (a) to (b) is about 3:1.
