Hydrogen Sulfide Generation in Shipboard Oily-Water Waste. Part 4. Minimisation of the Problem,

Abstract : This paper, the last in a series of four reports on an investigation into the environmental factors contributing to formation of hydrogen sulfide in shipboard oily-water waste, discusses approaches to minimising the problem. In particular, the importance of ensuring that the oily-water waste environment does not provide an optimal growth medium for sulfate-reducing bacteria, and that the quantities of sulfate available for reduction are kept as low as possible, are emphasized. Recommendations for changes to design and operating procedures which should achieve these aims are presented. jg p.3
