Diesel water flushing

[joisy]

1) Has someone experienced with the flushing of the diesel with portable water and follow-up separation (via centrifuge) of the dissolved water to delute and remove the soluted sodium hydroxide? We use the bubbling method!

2) How it can be better achieved: to add dimulsifier to diesel and wash with or to wash first and then add dimulsifier?

Thanks everyone beforehand!
