Abstract

Biological degradation of oilbased muds and production pit sludges are examined using batch reactors. Microbial populations from five different sources were screened as to their capability of survival in and degradation of the oils present. Two microorganism cultures, one developed from raw domestic wastewater and the other from a refinery biological treatment system, demonstrated superior acclimation and degradative properties based on substrate utilization and oxygen uptake rates. No toxic or inhibitory properties of the wastes were observed. Biological treatment has the potential to satisfactorally degrade wastes for disposal according to newly established Louisiana requirements, and also as a preconditioning step prior to conventional dewatering techniques.
