Just to confirm it will soak up water but not diesel?this one is much cheaper Cim-Tek Tank Dryer | Commercial Fuel Solutions Limited
but if you dont remove it quickly once it has soaked up the water it becomes a wonderful garden for bug breeding. not only collected the water together for growing but probably given them a nutrient bag to feed on.
and I certainly would not recommend drying it out for reuse because, you will just reintroduce a bag of bug spores into your tank ready to grow some good microbes.
so on the whole probably better to remove water by almost any other means is preferable IMHO
Its a surfactant additive ,there are a few fuelset is another, it does not magically disappear the water it allows it to mix with the fuel as the video shows , but surfactants are known to disarm coalescer filters so once you have used this NONE of the filters downstream will separate water even after you stop using the additive, there may be some separation by gravity but none by filtration. plus the dissolved water is passing through the injectors with the diesel with all the problems that may cause long term.I have started using this https://covalaquasolve.co.uk/ on the recommendation of a local fuel specialist that does everything from scores of standby generators to superyachts. If you already have water in the tank then this will only partially help but it will stop it building up.
hahahaha!I do not think Aquasolve is effective regarding water. The sleeve will only work under ideal conditions as the water has to be in contact with it in order for the sleeve to absorb it . Remember water is entering your tank every day as the tank breathes in and out. This water drains and collects on the bottom of the tank. The easiest way to remove it is to trim the boat so there is a low corner in the tank where the fuel will collect and then introduce a tube down to that corner and draw out the water. On my wee boat this is a doddle but on some boats may not be possible. Heaven knows why boat builders build very expensive boats that do not have drain cocks at the bottom of the tank. The water fuel interface is a great breeding ground for the bugs as is the interface surrounding all the droplets floating in the fuel.
Container ships do not use products such as this. They centrifuge the fuel before use however most of the water comes out by being drained from tanks prior to centrifuging.
I suspect that this was a double bottom tank where the dirty oil is stored prior to centrifuging and use. These tanks should get regular attention so maybe some undesirable bunkers had been loaded . Bet the chief engineer was peed offhahahaha!
Read this a couple of hours after reading a report from the super drydocking one of our container ships; one of the things on the dock list was to clean out a fuel oil tank and turn it into a gas oil tank. The report said that he found between a metre and a metre and a half of sludge in the tank! the purifiers hadn't sludged up so I make the working assumption that this was incompantibility. Bill for removing that lot is heading in the direction of the time charterers... We don't use scrubbers - we buy VLSFO....
(I do use Aquasolve, because I was persuaded into it by the outfit who last cleaned my tanks).
A good way to shift it is a hard beat into an F6/7 with the tank 1/4 full.I have found that sludge generally becomes immobile and stays in the tank or trap. It has to be mechanically removed. We built an exotic trap, about 6lt capacity. After ten years or so it contained 6lts of muck, despite regular draining. My small sedimenter had to be shaken to get the muck out.
I don't think that's entirely true, as water has some solubility in fuel.I do not think Aquasolve is effective regarding water. The sleeve will only work under ideal conditions as the water has to be in contact with it in order for the sleeve to absorb it ....
