Petroleum Bioventing e-bog

Petroleum bioventing is a new technique for the biological in situ removal of petroleum hydrocarbons from soil. This book investigates the composition and the behaviour of petroleum in soil, soil properties and soil processes, their interaction with bacterial processes, possibilities for optimizing the removal of petroleum hydrocarbons from soil by bacteria and it explains the phenomenon of recalcitrance. This interdisciplinary approach forms the basis for both modelling and design principles of bioventing. Key features: Background knowledge on the physical/chemical/biogeochemical properties of soil and soil processes with respect to petroleum bioventing; Background knowledge on petroleum biodegradation and noval approaches to stimulate petroleum biodegradation to stimulate petroleum biodegradation in soil and biofilters; Modelling efforts showing the effect of diffusion and soil porosity on bioventing design and the effect of ventilation quotients on the aeration & biological clean up of soils, particularly heterogeneous soils; New insights into biological removal of priority pollutants from petroleum hydrocarbons, the problem of residual concentrations of petroleum hydrocarbons in soil & the requirements by the Law on Soil Protection.
