Summary:The bioremediation of petroleum hydrocarbons has evolved into a number of different processes. These processes include in-situ aquifer bioremediation, bioventing, biosparging, passive bioremediation with oxygen release compounds, and intrinsic bioremediation. Although often viewed as competing technologies, these processes actually form a continuum of biodegradation processes governed primarily by the interplay between oxygen or electron acceptor and carbon availability. Generally, as more carbon needs to be removed per unit time, more oxygen needs to be supplied. As the carbon availability or desired removal rate decreases, so does the electron acceptor requirement. By understanding this continuum approach, bioremediation can be applied as a flexible, variable-speed technology, where the effort can be increased or decreased through oxygen supply. This article discusses the carbon-oxygen demands of each process and the interplay between processes, and then provides operating guidelines for configuring bioremediation systems for maximum flexibility.
