Service Overview

In addition to our tank cleaning services, we are delighted to offer a comprehensive fuel polishing programme.

When combined with tank cleaning, fuel polishing can reduce equipment breakdowns, and lower costs on consumables such as filters and injectors.

The need for fuel polishing can arise from a multitude of scenarios, the most common of which is a build up of water and sludge in the base of a tank over a period of years.

The waste in the tank then reacts with today’s modern blend of fuels to produce bacterial growth, commonly known as diesel bug. Click here for our article on diesel bug.


Fuel polishing equipment

Our range of accessible equipment allows us to offer both small and large scale fuel polishing services. The largest unit utilises a bank of six filters, beginning with 5 micron pots, before passing the fuel through a 1 micron filter to finish the process.

Up to 10,000 litres of fuel per hour can be polished with a larger unit, it is also equipped with an internal particulate counter. This allows up to the minute monitoring of the fuel being returned to the tank.

The single pot mobile filter uses a 5 micron coalescing filter to remove water and particulates. This unit is capable of polishing up to 3000 litres per hour, and is ideal for smaller fuel polishing applications.

A point to consider however, is the tank in which your clean fuel is being returned to. Fuel tanks are inherently dirty environments, which are incredibly difficult to empty without accessing it internally. Putting polished fuel back into a dirty tank can often defeat the object of the exercise, so we would always recommend thoroughly cleaning the tank during the process.


A lasting solution

The majority of tanks will have a fill pipe that extends to a striker plate at the base. An option being offered by many other companies involves putting a probe to the base of the tank and sucking out as much contamination as possible. Unfortunately this doesn’t deal with the often large build up of sludge at the ends of a tank, as a probe through the fill pipe simply cannot access it.

By cleaning the tank prior to returning the fuel, we are ensuring that your polished product remains clean rather than potentially becoming contaminated again.

  • Which should I use, concrete or foam?

    The reasons for using the two different products largely come down to the initial cost. Concrete does have a larger cost per cubic metre, however there is no mobilisation fee for the delivery. Foam has a lower cost per cubic metre, however the delivery of the product is subject to a fee. Larger tanks often tend to be more cost effective to foam fill due to the lower cost per cubic metre, with small tanks requiring just a few cubic metres can be cheaper to concrete fill.

  • What happens prior to filling a tank?

    If the tank being filled has contained petrol, the local licensing authority would be informed and a safe system of work submitted for approval. Upon receiving an order to proceed, our operatives would prepare the tank for filling by opening any required lids or flanges and ‘bottoming’ the tank. This process involves inserting a probe to the bottom of the tank in order to remove any remaining fuel that may reside below the suction lines. Once bottomed and vented, the tank is ready to have concrete gravity fed directly into the lid or foam pumped through a flange in order to fill the tank to capacity. A certificate of decommissioning can then be issued for each tank.

  • I have a tank that is solid filled, can I dispose of it?

    Tanks that have been filled over the years are classed as decommissioned, however substandard products used to fill the tanks can leave them in a potentially dangerous state. Towering concrete or sagging foam in a petrol tank can lead to large voids containing petrol vapours to accumulate. If cut using incorrect equipment, these voids do have the potential to cause an explosion and serious harm. Using cold cutting methods, we can safely open and vent previously filled tanks to ensure this doesn’t occur. Once safely opened, the product inside can be excavated and disposed of in the correct manner.
