Abstract:

<strong>ABSTRACT</strong> The rate of Total Petroleum Hydrocarbon (TPH) degradation in soil amended with mash food wastes (MFW) and fish wastes (FW) was investigated in this study. Experimental analysis was performed for a period of 56 days, while samples were collected weekly for analysis. The first and second order kinetic models were applied to study the TPH degradation rate. The result revealed that the rate of TPH removed from the control sample was low compared to samples amended by MFW and FW. Over 90% of TPH was removed from the amended samples, while only about 48% was removed from sa

Abstract:

There is a growing public concern as petroleum hydrocarbons are being introduced inadvertently or deliberately in large volumes into the environment thus causing a long term threat to all forms of life. Thus remediation of these is of utmost importance. The bioremediation technology is being employed for the degradation of crude oil in soil matrix through microorganisms which can transform petroleum hydrocarbons into less toxic compounds. In this study, optimum nutrients (C: N: P) concentration required for the microbial growth was investigated. The petroleum oily sludge, contaminated soil, so

The synergy of adsorption and photocatalysis is a good method to remove organic pollutants in wastewater. In recent decades, persistent photocatalysis has gained considerable interest for its ability to sustain the catalytic degradation of organic pollutants in the dark.

We found that the removal ability of TiO2, Ni-TiO2, and Ag/Ni-TiO2 is 8.8 mg/g, 13.9 mg/g and 23.4 mg/g, respectively, when the initial concentration of TCH is 50 mg/L.
