Abstract

Provided are biocidal compositions comprising glutaraldehyde and a compound selected from the group consisting of 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane; tris(hydroxymethyl)-nitromethane; and a hexahydrotriazine compound. The compositions are useful for controlling microorganisms in aqueous or water-containing systems.

Claims (7)

1. A synergistic composition against anaerobic bacteria comprising:

glutaraldehyde; and

hexahydro-1,3,5-tris(2-hydroxyethyl)-s-triazine

wherein the synergistic weight ratio of glutaraldehyde to hexahydro-1,3,5-tris(2-hydroxyethyl)-s-triazine is from 9:1 to 1:9.

2. A composition according to claim 1 further comprising one or more surfactants, ionic/nonionic polymers and scale, corrosion inhibitors, oxygen scavengers or additional biocides.

3. A method for controlling anaerobic bacteria in an aqueous or water-containing system, the method comprising treating the system with an effective amount of a composition according to claim 1 .

4. A method according to claim 3 wherein the aqueous or water-containing system is used or is present in oil and or gas production.
