The data sheet,
Aviation Fuels - Water and sludge should be removed from fuel tanks before application of the biocide.
100ppm v/v of KATHON™ FP 1.5 as supplied should be used to achieve microbial control, as described by EU BPD and US EPA regulations. To achieve this, the user should treat every 10,000 litres of aviation fuel with 1 litre of KATHON FP 1.5. The biocide should be added in such a manner so as to allow good mixing and distribution across the fuel. Ideally, this should be into a fuel supply line to ensure agitation. A contact time of up to 24 hours is recommended, depending on the severity of infection.
I presume your fuel is dispensed in litres, so a simple calculation to make if abiding by the data sheet. Seems Airbus may have overthought the procedure.

Looks like Kathon is being replaced with FuelClear AV15 - awaiting aviation approval. The company says "
Kathon FP 1.5 Fuel Biocide is being discontinued for aviation applications with immediate effect". Result of this incident?

Am I missing something? The Airbus manual talks about mixing by volume then uses weights for the calculation. One doesn't equal the other, specific gravity of the product is 1.04.
