FQS 1.5 Microbicide® - Pending Approval

FQS 1.5 Microbicide® is an EPA approved antimicrobial agent used in the control of bacteria and fungi in fuel systems that store liquid hydrocarbon fuels and oils such as: crude oils, petrochemical feed stocks, liquefied petroleum gasses, gasoline, diesel fuel oils, aviation fuels, kerosene, coal slurries, renewable fuel blend stock and renewable fuel blends.


FQS 1.5 Microbicide® has the same active ingredients as *Kathon FP 1.5 Microbicide.  It also has the same speed of kill, proven treat rate of 1:10,000, persistence and pricing.


FAST ACTING – FQS 1.5 Microbicide® has shown to decrease microbial activity in as quickly as 5 hours after initial treatment.


TREAT RATE: Typical effective treat rate is 100 ppm or 1 gallon FQS 1.5 Microbicide® to 10,000 gallons fuel product.  Fuel systems with severe microbial contamination can undergo treatments of up to 400 ppm.



EPA Registration No. 65597-1

MicrobMonitor2® TEST KIT

MicrobMonitor2® Test Kit is IATA approved and recognized by major airframe manufacturers for aviation fuel and is easy to use. You can test the water or fuel phase of aviation fuel. The kit consists of a test bottle containing a nutrient gel that promotes the growth of bacteria and yeast/molds. Once a sample has been added to the bottle, the container is incubated as instructed, dark place for 1 to 4 days for bacteria and 3 additional days for yeast & mold. The microbes actually grow in and on the gel. They will show up as red or purplish red dots in the sample bottle indicating a positive result. If you require a quantitative number there is a color chart to compare the results against.


Generally any positive growth requires action. Call FQS to consult on possible treatment options.


The MicrobMonitor2® can be used to test both the fuel/oil phase and the water phase.
