Preliminary process studies for bioremediation of PAH impacted soil
- Univ. of Akron, OH (United States)
Soil impacted with polycyclic aromatic hydrocarbons (PAHs) pose a major hazard to human life. To avoid further contamination, these soils need to be treated. The treatment can be chemical, physical, by supercritical extraction, or using other novel methods. The treatment choice is, however, governed by process economics. Biological methods are inherently very versatile, less expensive, and environmentally friendly. They operate at moderate conditions of temperature, pressure, and can be scaled up easily. It is of interest to do preliminary studies on the bioremediation of PAH impacted soils. The first step in a preliminary study is to identify the types and composition of contaminants in the soil. Then the physical and chemical properties data of these contaminants are considered. Based on these studies, a choice of microbial culture is made, from indigenous or acclimated strains of bacteria or fungi, which can efficiently consume these contaminants. Process conditions of temperature, alternate carbon and nitrogen sources, mixing, aeration, and moisture content were studied to achieve optimum contaminant removal.
