The NBS system is designed to prevent the formation of corrosive, damaging atmospheres in retail and commercial fuel storage tanks. The NBS system is an intrinsically safe Environmental Corrosion Control method that inhibits or prevents the growth of bacteria, molds and yeasts that may occur in the ullage of tanks and produce acidic deposits that cause serious damage and failures to tank equipment. Typically, retail tanks store routine and custom blends of diesel and biodiesel, gasoline and ethanol, and other commercial liquid hydrocarbon fuels. Additionally, these tanks are usually 50,000-gallon capacity or less, low pressure, and may be installed above or below ground.
