High purity 50% Glutaraldehyde solution CAS 111-30-8, broad-spectrum non-oxidizing biocide and bactericide. Widely used in oilfield injection water, produced water, industrial circulating cooling water, sewage treatment and aquaculture disinfection. Effectively kills SRB, iron bacteria and algae, prevents microbial corrosion and slime growth. Stable quality, complete export documents and bulk supply available.
Glutaraldehyde, also known as Glutaral or 1,5-Pentanedial, CAS 111-30-8, is a high-efficiency non-oxidizing broad-spectrum biocide. Our factory provides industrial grade 50% aqueous glutaraldehyde solution with low impurity, stable activity and long-lasting bactericidal performance. Different from chlorine and other oxidizing biocides, glutaraldehyde kills microorganisms by cross-linking microbial protein and enzyme structures, achieving permanent sterilization without easy drug resistance.
This product features fast sterilization speed, wide bactericidal spectrum and low corrosion to metal equipment. It can effectively inhibit and eliminate sulfate-reducing bacteria (SRB), iron bacteria, saprophytic bacteria, fungi and algae. It is the most mainstream and reliable biocide for oilfield water systems, industrial circulating water and environmental disinfection. It can be used alone or compounded with quaternary ammonium salts to form a high-efficiency composite bactericidal system, widely recognized in global petrochemical and water treatment industries.
1. Microbial Control:
SRB Inhibition: Reduces H₂S production by 90% at 50–100 ppm in oilfield brines, lowering corrosion rates from 0.5 to <0.05 mm/year.
Biofilm Destruction: Penetrates EPS matrix to kill embedded microbes in pipelines by 95%, reducing pressure drops by 25% after treatment.
Residual Activity: Provides 7-day protection against recontamination in recirculating systems, maintaining <10² CFU/mL bacteria count.
Broad Spectrum: Effective against aerobic bacteria (Pseudomonas), anaerobic bacteria (Desulfovibrio), and fungi (Cladosporium) at similar concentrations.
2. Process Compatibility:
High-Temperature Stability: Effective up to 150°C in steam injection wells, with <10% degradation after 24 hours at 120°C.
pH Tolerance: Works across pH 3–12, ideal for diverse water chemistries from acidic (pH 3) oilfield brines to alkaline (pH 11) drilling muds.
No Foaming: Compatible with surfactants and scale inhibitors (phosphonates, polyacrylates) without causing foam issues in pumping systems.
Low Adsorption: Minimal binding to clays and sediments (<5% loss), ensuring effective concentration reaches target microbes.
3. Environmental Compliance:
Low Aquatic Toxicity: LC50 >100 mg/L for freshwater fish (Oncorhynchus mykiss), meeting EPA aquatic life criteria for industrial discharges.
Biodegradable: Degrades to CO₂ and water under aerobic conditions (70% in 28 days, OECD 302B), reducing environmental persistence.
Regulatory Approval: Complies with API RP 38 guidelines for oilfield biocides and EU REACH registration (EC 1907/2006).
Glutaraldehyde 50% is the preferred special biocide for oilfield water systems. It is widely used in oilfield injection water, produced water, fracturing fluid, drilling mud and gathering pipeline systems. It efficiently inhibits sulfate-reducing bacteria and iron bacteria, controls microbial-induced corrosion (MIC), prevents pipeline perforation and hydrogen sulfide odor, reduces reservoir blockage caused by microbial sludge, and stabilizes oilfield water injection and oil recovery efficiency. It is suitable for long-term continuous sterilization of offshore and onshore oilfield water systems.
Widely used in circulating water systems of power plants, chemical plants, steel mills, pharmaceutical factories and manufacturing enterprises. It removes microbial sludge, biofilm and algae attached to cooling towers, heat exchangers and pipeline inner walls. It improves heat exchange efficiency, prevents pipeline blockage and equipment corrosion, and ensures stable operation of industrial circulating water systems throughout the year.
Used for sterilization, deodorization and sludge reduction in municipal sewage and industrial wastewater. It inhibits the reproduction of harmful microorganisms, reduces toxic gas generation, improves water body clarity, and assists wastewater reaching discharge standards. It is also applicable for disinfection and reuse of reclaimed water.
Serves as a high-efficiency water body disinfectant for fish, shrimp and crab breeding ponds. It kills pathogenic bacteria, fungi and protozoa in water, effectively prevents aquatic infectious diseases, improves water transparency, optimizes breeding water environment, and increases aquatic survival rate and yield.
Used for environmental sterilization of pig farms, cattle farms, poultry houses and hatcheries. It can disinfect breeding venues, feeding equipment, drinking water pipelines and air space, effectively reducing livestock and poultry disease incidence and realizing epidemic prevention and sanitary management of breeding bases.
As a high-level disinfectant, it is widely used for immersion sterilization of endoscopes, surgical instruments and non-heat-resistant medical equipment. It is also used for surface disinfection of sterile workshops, microbial laboratories and pharmaceutical production workshops.
Used as leather tanning cross-linking agent and textile mildew inhibitor to improve leather texture and fabric anti-mold performance. In fine chemical industry, it is used as protein cross-linking agent, biological tissue fixative and polymer synthetic auxiliary.
