Recently an “after” treatment sample of the 4000 litres of diesel fuel was tested by a major global company using an Australian laboratory, and easily passing the ISO 4406 standard (International Standard of Cleanliness for Diesel;2017) . ISO 4406 standard allows an upper limit of 200 parts per million (ppm) of dissolved water).
PFMBlue technology has treated some severely contaminated fuel, but even for us it was a record………
The diesel initial “before” test sample was found to have water burden contamination of 24,395 ppm, the water contamination was so high the fuel was not within the scale for ISO rating of water contamination.
The Diesel could been considered “industrial waste”, and a very expensive disposal and replacement exercise.
Upon completion of treatment, the water content was reduced to 101ppm of dissolved water and allowing for its ISO Rating achieving 16/14/10.
This level of contamination had not only the visible free water, but water entrained in the fuel at a molecular level. With physical removal using filtration and mechanical means (centrifugal) this type of remediation is not possible and would have had the fuel remaining non compliant with the ISO standard.
Therefore, use of these traditional methods alone will not achieve standards required by modern common rail engine design, older engines may also have a reduction of operational performance , if they could be run at all without damaging the injection pumps and injector nozzles.
Its just one of the issues water at very high pressures created by the Common Rail injection design can cause with damage to the fuels lubrication rating , carbon soot levels and general wear is increased, which may lead to immediate engine failure.
