Abstract
The report summarizes the results of biocide efficacy trials conducted over an eight year period (1984-1992) by Defence Research Establishment Atlantic, Dockyard Laboratory. The purpose of these trials was to determine which biocide or biocidal agent was most effective in the control or elimination of microbiological contamination (MBC) in distillate fuel systems. Growth, conditions, culture population (mixed or pure), percent free water present and sampling techniques were all found to have an effect on the measured efficacy of a biocide. In general the efficacy trials results indicated that biocides containing chlorinated and non-chlorinated isothiazolin-3 ones as the active ingredients were the most effective growth inhibitors of pure and mixed microbial cultures. Biocides containing organ-borate, as the active ingredient, exhibited the lowest efficacy. The effectiveness of the organo-borates was greatly influenced by the amount of free water present. The routine use of diethylene glycol monomethyl ether (DIEGME) combined with the practice of good fuel husbandry appears to be a suitable alternative to biocide use in systems where large volumes of free water are unlikely to be present.
