Abstract

This study investigated various ways by which the rate of biodegradation of hydrocarbons {ex-situ treatment} can be enhanced in an efficient, cost effective and environmentally friendly manner. To achieve this, bioremediation processes were applied to a crude oil impacted soil. Tests were conducted to evaluate the biodegradation effect of the oil on the soil e.g. effect on density, electrical conductivity, etc. The percentage of organic matter and carbon was evaluated in order to determine the organic carbon interaction with the contaminated soil sample. The effect of contamination on the geotechnical properties of the contaminated soil was also evaluated using compaction test. Two types of compost - sheep waste compost and crude oil (SCRO), and goat waste compost and crude oil (GCRO) - with an application rate of {0g, 350g and 550g} were applied in the treatment. The results showed that all bioremediation agents applied enhanced the natural bioremediation of the contaminated soil and the most preferred results were obtained when treatments were done using SCRO compost. This study revealed that the remediation process was influenced by application period, type of oil, and compost rate.
