Using magnetic fields to prevent microorganism growth
Microorganisms growing in fuel tanks are an increasing problem in the marine industry. They are commonly referred to as “diesel bugs” and consist mainly of bacteria and fungi. The microorganisms start to grow and form colonies whenever water is present in the fuel tank, and the introduction of RME as an additive in diesel makes the problems even worse. In a worst case scenario these colonies clog the fuel filters and/or cause an engine break-down at sea.
There are a number of available products at the market today to address this problem, mainly different biocides and different makes of filters with magnetic fields.
The main purpose of this thesis is to investigate future product improvements on fuel filters with magnetic fields used as a mean of controlling growth of microorganisms in fuel tanks. The thesis work will consist of three different main parts; the first part will focus on exploring the latest research results and explaining the theory of why and how magnetic fields affect microorganisms.
The second part will focus on laboratory tests of different fuel filters with magnetic fields (including the QL Decontaminator sold by Volvo Penta), i.e. create test cases and perform benchmarking tests against competitors.
The third part of the thesis work aims at combining the results from the theory review and laboratory tests and use those as a platform for new ideas to improve current products and suggest new applications.
