Abstract: 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 generation inhibitor treatment selected from the group consisting of ionophores, 2-mercaptobenzothiazole, alkanol amines, and mixtures thereof.

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.

Abstract: Lecithin and 2-bromo-2-nitropropane-1,3 diol (BNPD) are used to inhibit corrosion in boiler steam condensate systems. Aqueous steam condensate corrosion inhibiting compositions of these components are also disclosed. BNPD is also used as a preservative in lecithin containing and in other GRAS additive containing compositions.

Abstract: A method of controlling protozoa trophozoites and cysts is disclosed. The method comprises the addition of guanidine or biguanidine salts to aqueous systems harboring protozoa trophozoites and cysts. Addition of such materials to aqueous systems was found to be effective at controlling both the protozoa trophozoites and cysts. By effectively controlling both the protozoa trophozoites and cysts, organism such as Legionella cells harbored in both the trophozoites and cysts are in turn controlled.

Abstract: A method of controlling protozoa trophozoites and cysts is disclosed. The method comprises the addition of particular quaternary ammonium salts to aqueous systems harboring protozoa trophozoites and cysts. Addition of such quaternary ammonium salts to aqueous systems was found to be effective at controlling both the protozoa trophozoites and cysts. By effectively controlling both the protozoa trophozoites and cysts, organisms such as Legionella cells harbored in both the trophozoites and cysts are controlled.

Abstract: A bactericidal composition and method for inhibiting and controlling the growth of the capsulated, facultative bacterium, Klebsiella pneumoniae, are disclosed. The composition comprises an amount, effective for the intended purpose of diiodomethyl-p-tolylsulfone and 3,4-dichloro-1,2-dithiol-3-one. The method comprises administering between about 0.1 to about 200 parts of this combined treatment (based on one million parts of the desired aqueous system) to the particular water containing system for which treatment is desired.
