Opis:
In the article, review of the literature on the subject currently used methods of controlling or limiting the development of microorganisms in petroleum products was made. The problem of microbial contamination in petroleum products was presented, which is still valid and is becoming more common. In the article, microbiological contaminants present in petroleum products were described. In the following part of the article the various methods of combating microbial contamination in petroleum products, which include physical methods, thermal disinfection and chemical methods were presented. In due to the limited use of physical methods, the article focused on methods widely disseminated. Combating harmful microorganisms using a biocide were described, which due to their harmful effects on beneficial microorganisms and the environment are becoming more and more limited use. Because of their harmful effects on beneficial microorganisms and the environment, their use is becoming more limited. Furthermore, another method of controlling microorganisms during storage of the fuel by means of cleaners that help to eliminate the water, reducing sludge was presented. Apart from the measures to combat microorganisms and additives of cleaning properties, the simplified methods for determining the amount of microorganisms in the fuel using the kits containing the finished substrate suitable for growth of microorganisms are described. These kits allow the monitor the status of microbial petroleum products and thus help prevent many crashes. In the final part of the article authors proposed other ways to control or limit microbial growth are presented. The work conclusions were completed. The most important is that there is a need to develop effective methods of combating microbial contamination of fuels and oils by means of measures environmentally friendly.

Opis:
In this article, the problem of microbial contamination occurring in the fuels and oils was presented. It shows the types of microorganisms and the conditions for their growth. Then the factors influencing the growth of bacteria in petroleum products were described in detail. In the next section the symptoms, development and contamination of petroleum products was discussed. The influence of microbial contamination on the marine engine fuel system and the problems that this brings were also presented. In the following part of the article, the impact of microbial contamination of fuel tanks and purifiers was described. Then the causes of sludge were discussed and contamination layers in the settling tanks were presented. In the next part of the article the fuel impact modelling of microbial contamination on filtration efficiency was performed. The modelling presented in the article is an example showing how undesirable phenomenon is the microbial contamination and how pollution affects the other elements of the entire system. As part of the modelling, numerical model of filtration with the solution was presented. Then analysis results on the basis of the impurities concentration characteristics in the fuel as a function of the fouling thickness in the partition of the filter is performed. The development of impurities was divided into three stages. For each case the line trend and forecast further growth after the application of measures to prevent the proliferation of microorganisms were designated. The article was completed applications, of which the most important is the need to combat harmful microorganisms. And besides, there is a need to find new methods of combating microbial contamination that will not destroy beneficial microorganisms and will be environmentally friendly.

In this paper the concept of filtration and the problem of microbial contamination occurring in the fuels and oils was presented. Then the factors influencing the growth of bacteria in petroleum products were described in detail. In the next part of the article modeling of the impact of fuel microbial contamination on filtration efficiency was performed. The modeling presented in the article is an example showing how undesirable phenomenon is the microbial contamination and how pollution affects the other elements of the entire system. As part of the modeling, numerical model of filtration with the solution was presented. Then analysis results on the basis of the impurities concentration characteristics in the fuel as a function of the fouling thickness in the partition of the filter is performed. The development of impurities was divided into three stages. In the article for one case the trend line was presented. The article was completed conclusions.
