Remediation of Petroleum Polluted Site in Nigeria Using Granulated Activated Carbon (Gac)

Nigeria is a country prone to soil and water pollution resulting from the activities of the Oil and Gas industry. Remediating the polluted soil is very important hence the use of Granular Activated Carbon. Characterization of the soil samples before and after pollution was carried out using AOCS 1986 standard. Characterization of the commercially obtained Granular Activated Carbon before and after use was done using cultured Pseudomonas Putida. The remediation experiment was carried out for 14 days at temperatures of 30, 35, 40 and 45 o C with the initial total temperature and soil sample quantity valued to be 25mg/L and 500g. Graphical representation of remediation at different temperatures show that microbial degradation increases as temperature increases. The microbial degradation increases as temperature increases. The moisture content of the soil also decreases as temperature increases. Hence, hydrocarbon pollution leads to corresponding environmental impact on the soil which can be remediated by the use of Granular Activated Carbon (GAC).
