PREVENTION OF OIL SPILL POLLUTION IN SEA WATER USING LOCALLY AVAILABLE MATERIALS

摘要

Oil spill pollution, a severe environmental problem, which persists in marine environment or in inland water across the world, has grown to an alarming magnitude with increased levels of oil production and transport. The causes of oil pollution are categorized as either accidental or operational, wherever oil is produced, transported, stored, and used on the surface of sea or land. Hence, it is almost impossible for marine life to be free from the adverse affects of oil spill, though the discharge of oil is controlled by an international convention. Prime concern for the health of marine life has created an instinct for undertaking this study by the authors. Objectives of the present work include testing of four different local materials in separating oil from water having different oil concentrations, and their efficiency of removal. The work also focuses on effect of time of contact and dosage of materials used for oil removal. Corchorus depressus locally available has proved to be more effective when compared to other materials utilized in addressing oil-spill related problems. At the same time its byproducts do not give rise to unwanted hazards to marine life.
