a clean combination - MAHLE Industry - Filtration


Microbiological swabs ofinsufficiently dewatereddiesel samplesSurface damage inside aship's diesel oil tank“Dies el Oil Pest” – a serious problemDiesel fuel or lubrication oil tanks can becomecontaminated with microorganisms (bacteria,yeasts, fungi and algae) every time the tank isfilled or ventilated or if the contents are contaminatedby pollutants. Microorganisms canonly survive, grow and multiply in the waterphase of any medium. Water phases developduring storage and transport, particularly whendamp air inside the tank condenses.Microbiological contamination can have veryserious consequences, resulting in a loss ofdiesel and lubricant oil quality. The by-productsof microorganic metabolism block filter elements,diesel and oil pipes, water separatorsand injection pumps. The material of the tankwalls and pipes can also be severely damaged.Corrosion is further accelerated by water-solublesalts and hydrogen sulphide, a by-productof metabolism.Microorganisms can survive and multiply inwater concentrations higher than 60 ppm. Thehigher the water content in the medium, themore likely it is to become “infected”, resultingin a greater threat to the functionality and materialof the affected tanks, pipes and drive units.To prevent diesel oil pest: fuel treatmentWater concentration is the crucial factor formicro organism growth and the diesel oil pestproblem can only be addressed by reducing theamount of water in the fuel. This can be achie -ved by implementing continuous fuel and oiltreatment to prevent the water content from risingabove 60 ppm.Mechanical separators which use centrifugalseparation cannot provide the necessary levelof dewatering. None of the systems whichcomply with the applicable DIN standards orthe delivery standards of the mineral oil industryand NATO offer complete security, as theyallow a water content of 500 ppm and 100 ppmrespectively.A truly effective and lasting method of protectingfuel and lubricants against increasing waterconcentrations, and thus against contaminationby microorganisms, is to employ NFV fueland oil treatment systems.2

MAHLE Industriefiltrationdevelops and builds advanced filtrationand separation technology for use in awide range of industrial applications and inpower plants, civil and military ship -building.The company is part of the MAHLE Group,one of the top 30 automotive suppliersglobally and the world market leader forcombustion engine components, systemsand peripherals.NFV and AKO products are used in the followingapplications:Bilge water deoilingBallast water treatmentCooling lubricant and detergent processingIndustrial waste water cleaningSeparation systems (petrochem. industry)Oil and fuel treatment for engines, turbinesand gears; heavy oil filtrationProtection of hydraulic units, pipe lines,transfer and circulation systemsCAREFUL FUEL AND OIL TREATMENTPROTECTS ENGINES, TURBINES AND GEARSMAHLE Industriefiltration supports theircustomers with fuel and oil treatment systemsthat benefit from our more than40 years of experience. At the same time,we aim to lower costs while improving performance.The outstanding reliability of ourfilter coalescer separation technology is aninvaluable asset in tough day-to-day production.TurbinesAll over the world, gas and steam turbinepower plants that are fired with natural gasare increasingly being used as an alternativeto coal and nuclear power. The stateof-the-art,high-efficiency turbine technologyat the heart of these plants requiresspecially treated lubricants and control oilsto function optimally.EnginesPiston engines are the drive assemblies ofchoice for engine units that are in permanentoperation, e.g. ships engines andengines in combined heat and powerplants. The fuel used requires carefultreatment to ensure that these engines,and particularly the injection systems, canrun continuously for long periods of time.GearsIncreasing fuel prices are forcing manufacturersto design lighter systems using newmaterials. The construction of moderntransmission systems is far more complexthan a few years ago, and these systemsrequire specially treated lubricants withprecisely defined properties.5
