Fast Breaking Detergents: Their Role in the Generation of Hydrogen Sulfide in Oily-Water Wastes
2006
Fletcher, Lyn E. | Upsher, F. J.
Fast breaking detergents (FBD) have recently been commissioned for use in naval ships to facilitate separation of oily-water wastes (OWW). They replaced the earlier emulsifying detergents which were known to contribute to the bacterial generation of hydrogen sulfide in OWW. The present investigation was undertaken to determine whether FBD would also contribute to hydrogen sulfide generation. The formulations of the FBD indicated that they would be biodegraded by bacteria and thus power the production of hydrogen sulfide. This was demonstrated for two of the products; the third supported a large bacterial population but did not consistently cause significant hydrogen sulfide production. The potential for hydrogen sulfide production with the FBD examined was found to be less than with the earlier emulsifying detergents
