Glutaraldehyde 50%
Fast-acting dialdehyde non-oxidizing biocide specifically eradicating Sulfate Reducing Bacteria (SRB), anaerobic slime, and iron-reducing bacteria in oilfield produced water systems, gas transmission pipelines, and industrial cooling loops.
Technical Specification Target
Microbiological Cross-Linking & SRB Control
Glutaraldehyde acts by irreversible cross-linking with amine groups of proteins and nucleic acids in the bacterial cell wall, preventing microbial adaptation and resistance.
It is the industry standard biocide for eradicating Desulfovibrio and other hydrogen sulfide (H₂S) producing SRB bacteria responsible for microbiologically influenced corrosion (MIC) in oil and gas pipelines.

Frequently Asked Questions: Glutaraldehyde 50%
Expert technical answers on dosing, chemistry, handling, and application performance.
Q1. What is Glutaraldehyde 50% and what is its primary industrial role?
Glutaraldehyde (CAS 111-30-8) is a dialdehyde non-oxidizing biocide that cross-links proteins in cell walls, eradicating anaerobic Sulfate Reducing Bacteria (SRB) in oilfield water injection and cooling loops.
Q2. What is the typical dosage of Glutaraldehyde in oilfield waterflooding?
Standard slug dosing is 50 to 250 ppm active into produced water and injection manifolds. For pipeline hydrotesting, 100 to 500 ppm is maintained.
Q3. Why is Glutaraldehyde the preferred biocide against SRB in oilfields?
Glutaraldehyde penetrates sessile biofilms and rapidly deactivates the hydrogenase enzymes of SRB bacteria, preventing microbial-induced corrosion (MIC) and reservoir souring.
