DEVELOPMENT OF MICROBIOLOGICAL SLUDGE INHIBITORS
Abstract
A research investigation was carried out to develop information and materials for control of microbiological sludge formatio in jet fuel bulk storage tanks. A total of 184 microorganisms were isolated from jet fuel-water samples; 61% of the isolates survived viability tests. They appeared to fall into eight distinct groups consisting of five fungi (a brown type predominated) and three bacteria (transparent and opaque types predominated). Approximately 178 water-soluble materials were evaluated as potential microbiological sludge inhibitors. Three compounds are recommended for trial in bulk storage tank to control microbial growth. These are alkyl quaternary ammonium acetate, ethylidene diacetate and tri-n-butyl borate. Several others satisfactorily controlled microbial growth but contained elements that are potentially deleterious to fuel properties and fuel system materials. No appreciable changes in properties of JP-4 jet fuel were noted in storage tests of 90 days' duration involving jet fuel-mineral salts substrates with added microorganisms. (Author)
