Using Carbon Nanomaterials to Clean Up Oil Spills. Bioremediation is the process of removing or utilizing the pollutants from a particularly polluted area (like soil, municipal water tanks or sewage water, oil spills in water, or land) with the help of microorganisms like bacteria, fungi and also plants. Optimum pH is required for the bioremediation process which ranges from 6-8. Bioremediation is one of the most economic remedial techniques presently available for treating most organic fuel based contaminants such as coal tars and liquors, petroleum and other carcinogenic hydrocarbons such Each oil pit has its own characteristics & waste content. There are certain varieties of plants which have the ability to vacuum heavy metals the soil via root and concentrate them in the stems, shoots, and leaves. "Using Carbon Nanomaterials to Clean Up Oil Spills". Compost is a nutrient rich soil which is very useful in application to the crops and plants for their effective growth. Phytoremediation is another type of bioremediation that helps eliminate contaminants with the help of plants by repairing and regenerating the soil and ground and surface water. The microorganisms break down the compounds and metabolize them. The pollutants can be degraded by a consortium of microorganisms, e.g Pseudomoas, Corynebacterium, Arthrobacter, Mycobacterium and Nocardia. It is also a cost effective approach which requires minimal environment and energy for treatment of large volume of polluted soils. Stormwater is firstly directed into the designed treatment area, which conventionally consists of a sand bed (which serves as a transition to the actual soil), a filter media layer (which consists of layered materials of various composition), and plants atop the filter media. Usually the microorganism is indigenous, but occasionally microorganism that are very efficient at degrading a certain contaminant are additionally added.
