Separator solves issue of water in your diesel

One man who has come up with a solution to the problem of new low sulphur diesel absorbing water is Dutchman Theo van der Linden, of Micro Separator.

"The micro-separator is not a filter, but a separator that takes out 99.5pc of the water, including free water and water bound to the fuel by the bio-additive, and solid particles of sand, sludge or rust up to 50 microns in size," Theo said.

"This takes out the environment for the diesel bacteria to multiply, because the bacteria are the biggest problem. We find an average of about 150 species in fuel."

These bacteria have quite an effect on diesel, according to Mr van der Linden. "The bacteria transform the hydro-carbons in the fuel into hydrosulfide, which is an acid.

This acid wears down the fuel pump, the injectors and will break down the fuel into asphaltenes and tar. This is the black substance you will find in your filters."

The micro-separator is mounted on a tractor or vehicle between the fuel tanks and fuel filters. First, the incoming fuel is forced into a rotary motion through convector plates in the bottom compartment of the micro-separator unit. Using centrifugal force, the diesel and contaminants are separated without causing an emulsion.

The water and contaminants settle at the bottom of the separator unit where they can be drained through a tap at the base.

The fuel goes through a second phase in the micro-separator, travelling through three ceramic elements. Here, the remaining contaminants and water drops 'unite' and are fed to the bottom of the separator.

At the start of the year, Micro Separator developed the fuel stabilizer, a magnetic device which, as Mr van der Linden explains, "gives the cell layer of the bacteria a small charge so the bacteria are sterile for 3-4 weeks. After this period, of time, the bacteria will heal the cell layer and multiply again."

Mr van der Linden also said that common rail diesel fuel injection systems have a return fuel to the tractor's tank of about 60pc of the fuel pump capacity, effectively continually circulating the contents of the fuel tank until it is all used in work.

He claims that installing both micro-separator products will generate a clean and sterile fuel flow to the fuel tank and keep it clean.

The firm manufactures many different systems capable of maintaining fuel tanks up to 50,000 litres in size. For tractors, the 110-litre/hr system with both separator and magnetic stabiliser retails for around €600 + VAT.
