Standard Bio-diesel making process does use water. If the water is not removed 100%, long periods of fuel storage can create ideal opportunities for microbes to grow in fuel tanks; Microbes in the form of bacteria and fungus are present in all Bio-diesel fuels.

Bacterium that feeds on the Bio fuel/Bio Diesel component of the fuel is causing clumps to form in the fuel. These clumps are forming due to bacteria that feed on organic matter and release waste in form of sticky, wet and slimy substances. The clumps are causing damage to engines by blocking filters in the fuel system. Starving the fuel pump and injectors in diesel engine can cause damage that is expensive to repair. The problem is that if fuel storage tanks aren’t thoroughly cleaned out periodically by station owners, bacteria can breed in water that collects in the tanks.

In order to address the problem, station owners will have to get into a regular maintenance routine of thoroughly cleaning out the storage tanks to eliminate the bacterial growth.  A long-term fuel storage tank requires periodical testing for excess water.

Solutions: Many types of diesel fuel biocides have been used to treat this problem. So far none of the biocides are successful in eliminating 100% of the microbial growth. Many biocides interfere in combustion and initial starting of engine in the morning and at temperature below 40°F. Most biocides are soluble in water only therefore microbes that are feeding off fuel never come in contact with biocides. Adding biocides cause more harm than good.

Bio Diesel institute research shows that bio diesel blends of B2.5 and B5 are more susceptible to microbial growth than B100, possibly on account of the behavior of water, which comes into contact with the fuel. Microbes need water to strive, and because B100 is highly hygroscopic, it more readily absorbs free water, making it less available for microbial growth. Moisture control is key and there may be a role for use of appropriate biocides but only regard to their environmental impact. Biocides cannot resolve an existing heavy contamination and biocides alone will not resolve this problem.

Our product Bio Diesel Fuel Additive BD-4000 is specially formulated with Nano technology combined with eco friendly emulsifiers, additives, and moisture scavengers that reacts with hydrogen molecules in water and eliminates and prevents microbial growth. Also it creates internal Hydrogen bond Nano fusion, which ties up water molecules to help dissolve sticky substances within the fuel that causes filter and line clogging. Regular use of BD-4000 additive will keep fuel line and filter from clogging and solve line freeze and cold weather engine starting problems.
