Contact SupplierCrude oil contaminated soils were obtained from an oil pit in Burutu L.G.A. of Delta State and the Cow dung was collected from Garki slaughterhouse along Benin-Sapele-Warri road Delta, Nigeria.
Dec 2, 209 · Bioremediation provides a good clean-up strategy for crude oil-polluted soils, but bioremediation may not be feasible when applied to sites with high concentrations of chemicals that are toxic to microorganisms making experimentation with other clean-up methodologies desirable.
Crude oil contamination is one of the major environmental concerns and it has drawn interest from researchers and industries. Heavy oils contain 24-64% saturates and aromatics, 4-39% resins and -45% asphaltene. Resins and asphaltenes mainly consist of naphthenic aromatic hydrocarbons with alicyclic chains which are the hardest to degrade.
Crude oil contaminated soil from Isaka mangrove in Okirika local government area of Rivers state was treated with three different organic wastes (goat manure, poultry droppings and cow dung), for a period of 28 days. The four treatment samples were tilled twice a week and watered with 50 ml of distilled water weekly. There was a general increase in microbial count for all the treatments with ...
Aug 5, 2020 · Purpose The application of biochar to contaminated soil is an effective strategy to enhance soil remediation by promoting microbial activity. However, the insufficient bioavailability of petroleum in crude oil-contaminated soil limits its application in contaminated soil. Biosurfactant could improve the remediation efficiency of contaminated soil by improving the bioavailability of petroleum ...
iv) Crude oil-contaminated soil only (FS), if left for natural attenuation will take a longer time to degrade hence the need for bioremediation. v) The global problem of crude oil-contaminated soil is what this study has proffered solution to, through bioremediation technology and mathematical model.
Because soil contaminated with more than 5% Total Petroleum Hydrocarbon by weight of crude oil do not readily degrade [2], thus remediation was only studied at .5, 3.0, and 4.5% crude oil contaminated soil.This heavy crude oil contamination was equivalent to 3.7, 6.35 and 9.70litres/m2 of land area, respectively.Also, because bioremediation ...
Jun 5, 2020 · Bioremediation is widely considered the most desirable procedure for remediation of oil-contaminated soil. Few studies have focused on the relationships among microbial community, functional genes of biodegradation, and geochemical processes during field bioremediation, which provide crucial information for bioremediation.
This work was aimed at evaluating the relative merits of bioaugmentation, biostimulation and surfactant-enhanced bioavailability of a desert soil contaminated by crude oil through biopile treatment. The results show that the desert soil required bioaugmentation and biostimulation for bioremediation of crude oil. The bioaugmented biopile system led to a total petroleum hydrocarbon (TPH ...
May 27, 202 · Crude oil contaminated soils were obtained from an oil pit in Burutu L.G.A. of Delta State and the Cow dung was collected from Garki slaughterhouse along Benin-Sapele-Warri road Delta, Nigeria.
Biostimulation with inorganic fertilizer and bioaugmentation with hydrocarbon utilizing indigenous bacteria were employed as remedial options for 2 weeks in a crude oil-contaminated soil. To promote oil removal, biocarrier for immobilization of indigenous hydrocarbon-degrading bacteria was developed using peanut hull powder.
