OCCURRENCE AND BIOREMEDIATION OF POLYCYCLIC AROMATIC HYDROCARBONS (PAHs) CONTAMINATED SOILS

ABSTRACT

This research activity illustrates the use of bioremediation technique encompassing using a microbe in degrading prevalent PAHs contaminants in soil. PAHs are a group of organic priority pollutants of critical environmental and public health concern due to their toxic properties. The process involved simulation using ASPEN HYSYS. Various PAHs were selected and contaminated in 15kg of soil. The mixture was pumped into a tank whilst a microbe was injected and transported to a reactor for the complete mineralization of the process in the presence of oxygen producing carbon[iv]oxide and water, it could be noted that a high temperature of 1195F was observed due to absence of an enzyme. It could be seen that the concentrated of the PAHs reduced drastically in the bioremediated soil column. bioreactors is efficient and environmentally friendly in soil remediation.
